Proton is good, used them for years.
Personally, with all this “users can impact their privacy” stuff I see it as just part of a well used and much wider con, bit like political parties.
With political parties we have the illusion of control: We can vote this party out and that party in, and so we have control. But the reality is the parties are all the same, all working for the same people, all you’re doing is changing the personnel, the people with the power never changes.
With online privacy, give users the illusion that they have control over their online data and they will continue to make it available, just by a method that they wrongly consider to be secure.
Your mail is intercepted and ripped for data way before it hits you’re inbox.
Services like Proton may make it a bit harder for people to spy on you, but only a bit. In todays world any business that puts up real barriers to your data either get wiped out or bought out, normally by governments. Which is where my view on Apple stems from, and Google I suspect. They are all extensions of government. In return for their data Google gets to play with the low level data and make money out it, like Facebook, Apple get to commit massive tax fraud and get away with it.
