I did the same thing. The first privacy-oriented service I heard about was Proton. And, to be fair, they’re quite good. But the email search issues and struggles I had with their bridge eventually turned me off.
I left for mailbox(.)org and haven’t looked back. It’s great Proton has so many cool services, but the last thing I want is to get dependent on one company again, not after how hard it was to get away from Google.
I have to imagine the game was a disaster for them to abandon it like they did. Given what Cities Skylines 2 was like at release, their standards must be in the basement.
