Alternatives for the messaging app Signal

[Alessandro Greco]

I've been using Signal as a messaging app for several years now, but for a 
while now I've been noticing how this app is full of non-free code (at least 
this is what I could interpret) as countless Google services and libraries are 
used, moreover completely useless if you think it's a messaging app[1].
At this point I started doing some research for alternatives and found out that 
a decade ago there was LibreSignal[2], this project died due to technical 
support opposition (basically servers) from the creator of Signal[3], or at 
least that's what I could tell from the discussion there. And this makes sense, 
but I don't think those who wanted to use Signal would have resisted 
financially supporting the maintenance of the servers.
.. however ..
Getting to the point, I decided to write to this mailinglist to ask if there 
are any smartphone device users who can recommend me some free alternatives but 
more importantly if there is anything somehow “certified” by the FSF.
If nothing exists for the smartphone then I would settle for some libre desktop 
app.
