Signal is just as vulnerable to this as WhatsApp was.

No, they’re not. Whatsapp was never controlled by a 501©3. Selling everything off to a for-profit company isn’t a simple transaction, or else OpenAI would have tried that already.

They’ve also fought against any ways that it could be mitigated, they fought and are still fighting unofficial clients (moxie himself went around harassing people to stop), they fought any form of decentralization or interoperability with other servers and self-hosting.

If you go and read the reasoning, it makes sense. Part of it is the enforcement of their internal standards (like not storing chats for longer than it takes to deliver them) and part of it is that it would require rebuilding almost everything. It was never designed with ad hoc server participation or self-hosting in mind; you can’t just drop in an API on top of existing software.

I agree that centralized chat is a potential chokepoint for capitalists to enshittify things, but people are crucifying Signal for something that hasn’t even remotely happened.

If it does, there’s lots of options out there that are getting better all the time. My backup plan is SimpleX. But Signal still seems to be delivering what they claim, and it’s a lot easier to get non-technical people on board with encrypted chat via Signal than many of the other options, currently.
