That’s what Google wants, because people gave up on Jailbreaking iPhones because the loss of features wasn’t worth it on the other side. Google probably doesn’t love that their flagship is the best model for use with custom ROMs, plus they’re also trying to lock out Xiomi as well for what that’s worth.
While giving up is an option, someone somewhere needs to coordinate this entire OSS ecosystem to focus on singular projects. I would love to see a privacy and FOSS non-profit do exactly this.
This is kind of useless fear-mongering suited to no one’s threat model.
Are messages truly E2EE and they don’t share meta data? Yes? Then you’re fine. It needs a phone number for registration? OK, well buy a burner SIM card (you of course have several, right?) to register it if you’re that worried. Because if you’re already at a level where you’re THAT concerned about your phone number pinging for using a widely popular messaging app, then you have lost the game by even having a phone or sending messages to other humans who are the weakest link in the security chain anyway.
Considering that the Feds tried to make some government-compliant front end for Signal for idiot Hegseth to use to talk about national security stuff with the Vice President, I’d say that it’s probably fine for you to buy weed or whatever.
