Seeing lots of posts about people using #Signal and trying to get friends and family onto it.

This might not be a good idea, here's why:

-Signal is centralised.

-Centralised services are difficult/impossible to leave, because of the network effect.

-Centralised services can be sold to other people without warning.

-The guy who runs Signal is a billionaire who sold WhatsApp to Facebook in 2014 (that's how he became a billionaire).

What will you do if history repeats?
