What proton offers as a paid service is compelling. It does give you the opportunity to provide metadata that can be used against you, which is how the legitimate concern over its cooperation with law enforcement played out.

I would recommend against choosing security or privacy services based on the politics of their c-suite. In a lot of ways it’s similar to getting firearm training or equipment. You might feel like you’re materially supporting your enemy, but specifically in this particular political moment you aren’t in a position to sus out the depth or veracity of someone’s expressed politics and the point is to get the right understanding, equipment and systems, not to vote with your dollars.

Further, you want to understand how the system you’re purchasing access to works. Email, for example, cannot be private without some sort of additional cryptography. SMTP is best effort only, and even in the case that the system doesn’t fall back to unencrypted transmission, it relies on certs that are often spoofed by the end users isp as a matter of course and allow mitm attacks.

Information input to an llm will be used as a training dataset later on down the line so that means anything you use the llm for shines the panopticon beam onto you.
