This is my personal opinion and only that, my opinion. If your options are proton or Google, proton. If you have the ability, technical ability (in some cases), and mental bandwidth to diversify those services, that's even better. And if you want to securely and properly self host your own options that match your specific threat level, that's the best.

I personally use paid proton for my email. I occasionally use the free VPN, and I have several things in their drive as a backup to my backup of my backup. I personally would not put all my eggs in the proton basket because I did that in the past with Google and if we're ignoring the privacy portion, they have discontinued so many things over the years that I learned not to put ALL my faith in ONE company.

Edit to add, I also didn't even touch the CEO thing but I see several others have. If we account for that, I'd still say it's significantly better than Google.
