I believe your technical understanding is flawed

Its interesting that you assumed that my objections stemmed from technical problems. Why is that?

Its not, its from usability and trust and poor decisions.

The fact that they're going to run out of money and the entire platform will just cease to exist is itself my primary objection, much the same as Signal and other centralized services.

The fact that it even costs so much to run is another.

And thirdly, their involvement in crypto shenanigans is an instant dealbreaker.
