I mean, I can see why it's brewed an anti crowd. Founded by Radio Free Asia, a USA propaganda arm, and was funded up until late last year.

Additionally they have been aggressively pushed by the NED, an organization created to effectively conduct CIA color revolution in the overt.

And finally, compared to the other major US developed and funded project Tor, it is very centralized. It requires a phone number to use. The open source code is very oftenly neglected with the repository being out of date compared to the code being pushed out in updates.

Not every non-profit is your friend. Especially not non-profits that recieve funding largely from an agressive state that fashions itself as world police.

Now, I do use it as the US government is not currently in my threat model and I'm in need of an accessible messaging platform that I can get friends, family, and coworkers onto. But if for instance, the next administration extends transphobic policies federally you best believe I'm keeping that information off Signal.
