Hear hear. It really is an absurd world we live in, and I had a good chuckle about that - just before I deleted my Keybase account.
In the post Covid world I was forced to compromise a bit and I will join a Zoom call in a browser (when it works) or install the app on my phone if I have to. I trust iOS to not get totally owned by a rogue app more than anything else I have available. Although recently that's not an entirely safe bet either.
Keybase was not critical to my daily life so it will not hurt to get rid of it. It's about risk management. There are no upsides to Zoom and almost no upsides to Keybase (for me). With the growing list of downsides it's an easy choice to make.
Why do I owe a commercial enterprise anything? They demonstrated repeatedly they cannot be trusted. In obvious and extreme fashion.
The fact that Keybase agreed to this tells me a lot more about Keybase than it does about Zoom.
My first reaction was: it can't be that keybase can it? Huh, well maybe I'd sell my principles for that much money too, oh well.
Maybe some keybase employee will end up being a whistleblower sometime soon though.
Zoom already has end to end encryption according to some of their other press releases and public statements (we know they don't), so why on earth would you believe this one?
I don't quite get the purpose though, why would I post something in public only for a group of people to be able to read it? Why not post it in a private chat then (encrypted, naturally)?
Keybase solves a (to me) nontrivial problem: How to bring private keys into social media. Just a silly example: You don't use the same private-public key exchange in Whatsapp as you would use for your emails, or to sign your packages. It's a bit of the now infamous Dropbox situation: Most people can sign things with private keys and properly keep track of it, but they don't get around to doing it. It's only critical cases where the use is common (like signing packages). It took a long time even for HTTPS to become standard practise, though I guess the situation with your browser is a bit different.
