Stop switching to every new "cool" and "encrypted" service every time the previous one disappointed you a little bit. This is not helpful neither for your time, nor for privacy community overall. We should lean on most developed and best platforms we have right now (Proton, Signal etc.) and get everyone to switch. Unless we know we have market dominance, dispersing our efforts is futile.
