I also pay for Proton for mail (anything that requires a credit card or bank account) mostly, tosser e-mails and vpn once in awhile as I have a gmail account strictly for Chrome/YouTube and an old yahoo account of spam control. Other than that it's mostly open source - ZorinOS, Bitwarden, KeePassXC (encrypted vault mode), Ublock Origins, Liberwolf, LiberOffice, etc.
You will never see an encrypted Discord not because it can't be done right this moment but because that is not what the company is doing. I don't think Discord is what you think it is.
As for /Privacy, it's mostly children and idiots flailing in the wind. They want the idea of privacy but not the work or limitations of it. An easy example is how they ban any mention of GrapheneOS or LinageOS both the only sane option to pick for a pixel phone (I run Graphene on my Pixel 8 Pro).
