People suggest matrix but matrix really doesnt replace mattermost for an org.

mattermost is oriented towards org needs. It has boards, playbooks, better levels of access control. Admin panels etc.

We really need a sane Slack alternative that is at least fully free for self hosting.

I honestly dont know at this point. but my point is, people buying phones of THE evil company that takes our freedom and privacy away, to get freedom, and think that a company as evil as google will just let you have actual privacy, is kind of absurd. But, it seems like you people have done more research on this. You say there is and havent been evidence of spyware on google pixels, and I will accept that. But deep down Im pessimistic.

Seems people are pretty confident about that. I guess I am too pessimistic in tech to accept governments and big tech will allow you to have a spyware free phone by any means, but I havent done actual research (Im not a security researcher anyway) into it. So I accept the wisdom of people here.

Ever heard of hardware backdoors and spyware?

Very wierd of you to assume there will be spyware on samsung but not google phones
