It was reported in Brazil last week that the Federal Police was able to access previously displayed WhatsApp “view once” messages during an “extraction carried out by specific software that jointly displays the messages and files sent, reversing, in practice, the single view of the message” .

Here follows the original report, in Portuguese, and a quick translation to English.
Emphases and text within square brackets on the translation are my own.

Original Report
> Mensagens trocadas entre Vorcaro e Moraes foram extraídas e periciadas pela PF, diz jornal
> > Reportagem publicada pelo blog da jornalista Malu Gaspar, do jornal “O Globo”, trouxe prints de mensagens atribuídas ao banqueiro Daniel Vorcaro enviadas ao ministro Alexandre de Moraes horas antes de Vorcaro ser preso pela primeira vez.
> > O jornal o Globo publicou, na noite desta sexta-feira (6), uma reportagem informando que os dados das mensagens trocadas no dia 17 de novembro entre Daniel Vorcaro e o ministro Alexandre de Moraes, do Supremo Tribunal Federal (STF), foram retirados do celular do dono do Master por meio de análise técnica da Polícia Federal (PF), e que essa análise permite visualizar, ao mesmo tempo, a tela de whatsapp com as mensagens e as imagens de visualização única nela contida.
> > O jornal informa também que, diferentemente do material enviado à CPMI do INSS, o conteúdo a que o Globo teve acesso não é fruto de comparação entre os horários dos textos que constam em blocos de nota de Vorcaro e as mensagens enviadas por ele, embora coincidam, e sim resultado da extração realizada por um software específico que exibe conjuntamente as mensagens e os arquivos enviados, revertendo, na prática, a visualização única da mensagem.

English Translation
> Messages exchanged between Vorcaro and Moraes were extracted and examined by the Federal Police, says newspaper
> > A report published by journalist Malu Gaspar’s blog, from the newspaper “O Globo”, brought prints of messages attributed to banker Daniel Vorcaro sent to minister Alexandre de Moraes hours before Vorcaro was arrested for the first time.
> > The newspaper “O Globo” published, on the night of this Friday (6), a report informing that the data of the messages exchanged on November 17th between Daniel Vorcaro and Minister Alexandre de Moraes, of the Federal Supreme Court (STF), were removed from the [banker’s] cell phone through technical analysis by the Federal Police (PF), and that this analysis allows viewing, at the same time, the WhatsApp screen with the messages and the single-view images contained therein.
> > The newspaper also informs that, unlike the material sent to [a National Congress investigation], the content that “O Globo” had access to is not the result of a comparison between the times of the texts contained in Vorcaro’s notebooks and the messages sent by him, although they coincide, but rather the result of extraction carried out by specific software that jointly displays the messages and files sent, reversing, in practice, the single view of the message .

Using Yattee, Invidious & Tailscale to give Google the finger

Everyone knows that YouTube is a hot mess when it comes to privacy, and I finally got fed up with having to shell out my hard earned money for YouTube Premium. It wasn’t too dificult to find a reasonable solution for my Fedora system… just pop into Gnome Software and install Pipeline. Problem solved there… no tracking, and I only had to deal with the occasional sponsor message in a video. I’ve also got UBlock Origin, Sponsor Block and Dearrow installed in Fire Fox, so things are solved there too. The problem was my iPhone, and how to work around the ads in YouTube there. Thankfully, a little research lled me to an app/server called Yattee. I found a few guides in their documentation about how to install it (it assumes Docker, but I have Podman on my Fedora system and had to modify some instructions slightly to take SELinux into account), and I successfully got it set up. I did have to connect Yattee to an Invidious instance, but that’s quite straightforward to do. Finally, I used Tailscale Serve to create a reverse HTTPS proxy in front of the Yattee server hosted via the Podman instance so I could access the server from the client app on my iPhone regardless of wherever I happen to be. I’ve tested it out, and despite the client being a beta (v2.x) and the server being fairly new as well, it allows me to enjoy YouTube videos without Google’s privacy-invasive BS. Two final notes: 1. The server isn’t exposed to the public internet, and is only available over my tailnet. 2. I use a public Invidious instance, but the integration isn’t for the actual retrieval of videos (that’s handled by the Yattee server, which is YT-DLP based), it’s more for search and metadata retrieval. Maybe not a perfect solution, but it does the job I want it to do.

Yattee Server is just a YT-DLP based back end for Yattee 2.0 (which is currently only available via TestFlight). Yattee 1.0 was actually pulled by the dev from the App Store because it was out of date and broken. Being blind, I can’t tell you the resolution that videos play in, but at least for me they play smoothly with some rare stuttering. From what I can tell, setting things to proxy the videos Directly through Yattee Server leads to a temporary download that lasts for 24 hours, but the playback is slow to start due to the requirement of the download needing to occur first. Once it does play, then the experience is as I described earlier.

Well, this explains that, I’m stuck with Yattee 1.0, which seems to work for me, or at least has the same bugs as Invidious/Piped.
