Take a look at the security functions the Pixel platform hardware provides. It isn’t optional.

GrapheneOS is Android though.

I’ve also thought of that option, since it offers flexibility and allows better receiver placement.

Thanks for the suggestion, but I was thinking of continous, transparent position fix acquisition.

No, Revolt checks neither of my boxes unfortunately.

End to end encryption between clients (also for groups) seems to partly address the issue of a bad server. As for self-hosting, any rented or cloud sevices are very vulnerable to an evil maid. So either in-house hosting or locked cages with tamper-proof hardware remain an option.

What’s the protection in the clients assuming compromised infrastructure, like e.g. in https://notes.valdikss.org.ru/jabber.ru-mitm/ ?

It is entirely insecure.

So what’s left? Jabber?

While I use Vanadium, it doesn’t support the basic Firefox plugins.

To hell. In a handbasket.

You still don’t?

Dunno, for now Ironfox and Vanadium as a fallback work for me on mobile. I’m open to alternative browsers when the upstream fails.

No use cases for this so far.

Mobile service quality is defined by the baseband, which is an immutable blob to the OS. I phone rarely and currently use my old LineageOS phone for it.

I’ve got a support case for my Pixel 7a open due to potential battery issue. If I return it I will buy a different, bigger (6.7") Pixel model. My new Pixel tablet is doing fine so far.

I use tablets to read things when lying down, so notebooks don’t fit.

Matrix (Element), Signal, Telegram. Other stuff probably requires Google services which I don’t use on the tablet. Phone has Google services, but I don’t really use it for messaging other than Signal.

The endgame is that nobody has money and companies go bankrupt. The end.

I’m on GrapheneOS on tablet/phone for time being, but I’m fine going back to a dumphone and a Linux or BSD tablet or convertible.

Side effects became too annoying. My job is currently not sufficiently stressfull, so I can do without. Not getting stuff done is a tradeoff, but I’m too old to care.

I was on atomoxetine before it suddenly stopped working, then on methylphenidate which only fucked me up and then on lysdexamfetamine which worked best. I have been off medication for a few years now.
