Proton has the burden of proof, and has continually failed to ensure their systems are E2E. They have failed to develop better tech like signal, and continue to change their infrastructure to appease swiss orders that come from other countries.

They have every means to decrypt, they control both the client software, server, and data. You would never know if they logged your key, and they can be compelled to by flimsy order.

This is inaccurate. First, Swiss law does not allow the breaking of E2EE. All of Proton's client side code is open source. We cannot arbitrarily change keys in an undetected way due to Key Transparency: https://proton.me/support/key-transparency. We also have open source mobile and desktop apps, so you don't even need to rely on the web app if you don't want.
