I absolutely hate how new messaging tools are always mobile-only.
I don't trust mobile phones hardware and I don't trust their software either.
I have no need to have my movements and connections to people tracked 24/7 and I have even less need of supplying messaging apps with globally unique identifiers associated to me (like, you know, a *phone number*).
IMO this is the main weakness of pretty much every messaging app of the last decade and it'll bite y'all in the arse sooner or later.
