API shenanigans and/or CAPTCHA breaks hydroxide (the foss bridge)
protonvpn: you can no longer fetch all the configs in one download. You have to click “download” >120 times now to get all the configs
account locks if you do not login frequently enough (i think every 6 months)
if you supply your login creds but get a CAPTCHA and say fuck this, and walk, it does not count as a full login needed to reset the expiration clock
the CAPTCHAs are graphical which forces you to enable images in your browser; but when you do that you get images that junk up your screen and waste bandwidth
no public keyring. Hushmail was better in this regard. An advanced user could upload their PGP public key to Hushtools and then encryption just worked for hushmail users contacting that person. After Hushmail started charging, I would tell the normies who need comms w/me to get a gratis Protonmail account. But then I have to send them my public key and they have to figure out how to attach it to my profile in their phonebook. It’s a show-stopper in many situations.
