This article also just points out the use of Livekit but doesn't deliver what that means for your security. Maybe instead of writing a hit piece you could have dug deeper, talked to Proton?
I've seen alot of articles and posters here being negative on Proton, calling it "shady", regurgitating facts that are supposed to be gotchas but have tons of nuance if you dig and am beginning to think there is some coordinated effort to get people not to use it.
