Privacy has been beaten to a bloody pulp, but the fight doesn't need to be called yet. Don't give up, keep telling everyone you can. I know things are looking low right now, but every person you reach matters.

In the case of Zoom, an approach that could actually work is having every step of the solution already completed if you've got an employer trying to push Zoom on employees. Make sure you can clearly state here's the problem, here's why it's dangerous for the company, here's a great alternative, here's why it's safest for the company, and here's how you install it. Reach out to the IT dept if you're not the IT dept to get them on board. If the advice is coming from multiple employees, that will help your case.

I have gone back to using XMPP and have my family and friends using it. There has been a uptik in development of this protocol and the mobile apps have gotten way better. Facebook, whats app, google, and countless others all started with XMPP/jabber and they all could talk to each other. That is until they walled them off to try and force everyone on to there app. Its so dumb that we had a federated chat system that was taking hold until the big tech players got involed and sucked up the users then turned off federation. Chat could and still can be like email if there is critical mass on one of these federated protocols so everyone will start useing it.

My phone number is run though my XMPP server, no matter what phone or computer I use I can access my phone number. Hell I could drop my phone plan all together, if I wanted to and just use wifi for calls. 90% of the time im connected to wifi anyways. I use jmp.chat and the android app cheogram you should check it out.
