GPG sucks. I use it, I have a smartcard, I did subkeys, etc. I encrypt backups, I log with it to ssh. And it sucks. It sucks so bad, that I don't even know why I am doing it. There are just so many technical glitches, not to mention all the googling, FAQs, manuals that I had to bookmark and constantly refer to, to use it.
Running your own server just shifts your trust from Google to DigitalOcean/Linode/AWS or your residential ISP (even less deserving).
I wish we would stop this navel-gazing about which providers to trust and FUCKING ADOPT GPG ALREADY. It's been, what, 15 years?
