I’d rather use a Swiss messenger than basically any other country, but yeah Threema is not mainstream and might as well not exist to most normals.

I’d trust them personally over any other country though, and I did once make my own messenger that used a few different encryptions (main one was serpent) and 2 passwords (using a lot of variations on both with slightly dif encryption types in multiple rounds which I’ll be honest was slow) . But yeah most normal people need to at least know something is mainstream/popular before they will ever install an app.

USA is circling the drain, when other countries drop the dollar for oil trades US is going to invent 4th world debt.

I use signal but if I could convince everyone I knew to use a messenger for security it would be Threema. No chance of that happening it’s hard enough convincing people to use signal.
