I would participate in the Proton Charity Fundraiser. You can buy tickets which would allow you to win Proton lifetime account and at the same time, you would support really cool FOSS projects, such as: GrapheneOS, Qubes OS, Tor Project.
Proton is fine, but their Charity Fundraiser is awesome: https://proton.me/blog/2022-lifetime-account-charity-fundrai...
