Preaching to the choir here. Been an righteous advocate for FOSS for almost 15 years.

Personal devices are all FOSS, or GTFO. 

Work forces me to use only 2 proprietary applications. I loath having to use that many.  

 agree, thats why we need nostr based solution. People ephasizing how "secure" is ios or signal app forgot that security without freedom is temporary and accidental. 

 Properly implemented like keychat would be good. But it can be done without nostr too as Simplex is already becoming mature 

 yeah, but no. Nostr is horizontal and decentralized from day zero, simplex is a platform well documented unless people start doing third party implementations of clients and server.
I think projects that start like simplex dont end decentralized and open. Would be happy to be wrong! 

 Yep. Even keychat on Nostr is likely to get centralized over time. 

You either incentivize multiple clients, multiple servers, which goes against the duty to maximize revenue of a company, or you end up centralizing everything. 

 There are a lot of servers outside the pool the run. I run two of my own
