Proton is the most shady company out there, especially with the fact that they try to make you put all your eggs into their basket. I stopped using their email (when they used to be an only email company) when they dropped the .ch domain. Same goes with botched security products like grapheneOS and the likes, when the hardware is backdoored, the modem is tracking you more than your psycho ex, yet you are given these illusion of security to buy.. you are not, in fact, you are gonna get more obvious for fingerprinting than using an average iPhone like most people and blend in. Honeypot, hornets nest, whatever the terminology but the concept being used and is still used to lure people in and make the job easier to ID them than going after them in the wild.

What do you use/recommend that are better alternatives?

They definitely still have the .ch domain
