Its a 18 months old but OP means this on the same site. https://マリウス.com/if-you-must-use-signal-use-molly/

The blogger also stopped using proton mail. So idk. Seems to be their thing atm.

Tried this 6-9 months ago and it was a shambles that I could hardly get working.

The main issue (once it was working) was program (Stremio) not supporting keyboard only options.

I also wanted to run android apps full screen (like a dog nvidia shield) but it was chaos.

I thought it was abandoned.
