It's fair to be suspicious of astroturf. FWIW I am a Proton user, but I get no benefit other than self-soothing from criticizing proton criticism.

My main beef was with the writing style, which is so over the top and repetitive and seemingly AI-generated that I couldn't stand it.

Proton Meet relying on a bunch of US infrastructure is something they should call out themselves loudly when they advertise it, to be sure.
