I can't recommend downloading from sources to normal people, and the problem is no, one step after step is better, as you can't have a perfect solution for privacy btw, but moving from one service to one service lets say in one day, week or maybe even month is not realistic. Its like recommending a password manager, great, but then saying theres immediat need to change all password... Like, technically true, but realisticly, bank and mail firsts, then step by step some passwords, without forgeting new accounts should have now strong passwords.

As I said, ie my girlfriend knowing Im interested into privacy tell me that she just installed and created a protonmail account and she used Drive a bit, if I just say thats useless because there need compartimentalization and Proton gave IP to police, thats fckd up

The most private, the most secure option isn't for everyone, first to threat model, second to personnal daily life

A person interested can still have Gafam apps, for some needs, required, but can limit the settings.

If you are a gamer, you mostly still need Windows computer (Linux got better and better, depends on games tho), then you can choose to say fck, or you can use it with limiting the stuff you can (turning off maximum settings you can, OsU10, etc.). Thats the same with iOS.. Most people wont buy right now a new phone because of privacy, but maybe the next in few months or in 2 years ; doesnt mean during this period you can't choose apps to use, turning off iOS features, etc..

For some projects I needed TikTok, I wrote myself a guide, to use it as anonymous as possible, to TikTok and to people, instead of using it raw, defaults
