I don't like Google, the company, and if there is an easy option to migrate to that will cause me the least usability issues, I'll migrate.
Call me a lazy activist if you will.
Any good alternatives that don't look like webmail from the 90's?
Another option could be to skip webmail and use local clients instead, like Mail.app or whatever you fancy.
No reports of Fastmail-sent emails getting dropped like I heard one time about Proton-sent emails (I think I saw that in a comment in HN, and only one anecdotal report, so who knows if it's true or not).
Fastmail also does contacts/calendars/file-hosting (which includes the ability to do simple photo sharing and websites).
I've used their support when I got confused about something, and they were very helpful.
Idk about your style preferences though.
Edit: Hm, https://www.fsf.org/resources/webmail-systems this link below seems to say proton has javascript vulnerability...
As any legally operating company, we need to comply with the local legislation. However, do to the zero-access encryption we use on our servers, there is very limited data we can provide in case of a data request. Particularly, we cannot share any of the email content (including attachments, content of your calendars, password, files stored on Proton Drive) in an unencrypted form, because we have no access to those ourselves.
