I think because simpleX is more open source, self-hosted, and maybe slightly more anonymous. Not sure how the usability trades off for that if at all because I haven’t used it (I mainly use signal and discord)

It also doesn’t seem to be a mass migration by any means, just that simpleX is a bit better if you are super hardcore about your privacy.

It was initially a pwa, but now it is a full and proper app, even available on Google play now!

I believe it can still be used as a pwa though.

In theory it should be mostly fine to touch, idk much about it either unfortunately. it might be a good idea to put some sort of spray on sealer if you will be touching it regularly and are concerned about it at all.

It is definitely dangerous to sand or cut with a saw or something, definitely want to do that outside with gloves and a respirator because then you’re getting loose fibers both on you and airborne.
