Element definitely ticks all the boxes that i have on my list. of course everything can be MiTM’d by taking the devs hostage or handing down legal filings against ISPs, but in the overall scheme of things, it’s best to distribute over various networks under various accounts, putting the data together is usually an overreach if you are not outright violent or criminal which i don’t assume anyone on the far left to be, at least not by ideological design
