Firefox died long ago.

It was an engine fight, and Mozilla decided not to participate.

You’re the asshole to the normal extent that anyone who makes an excuse to skip a party is an asshole.

That being said, a party thrown by someone who is trying to be conspicuously wealthy is an excuse to drink for free, so skipping it is kind of lame.

I’ve got a couple VPSes, hosting

• Mailcow, because email is identity.
• Asterisk, because phone #s are also identity.
• Matrix-Synapse, for personal messaging even though XMPP is probably better.
• ttrss, even though it’s junk software with a jerk developer.
• A bunch of self-developed web apps

Self hosting email is obnoxious, but it’s also one of the only remnants of the traditional distributed internet that’s still broadly accepted.
