I try to avoid using any services that try to analyse my behaviour (so no music service like spotify, no video service like netflix, no social medias, no closed messaging service...)
I use ublock on my browsers in paranoid mode (block all third parties and having to whitelist what's needed for a website to work)
My phone is an android on which i've installed lineage with no gapps and i use fdroid to get apps
All this is a pain to manage (at least i learnt a lot managing all this) and can't definitely be done by people who are not interrested by the technical side
It's also quite restrictive and definitly cut myself from a lot of friends.
I still find it worthwhile though and am not interested in stopping hosting my own services.
For me the main issue is that the web isn't privacy friendly at all by default, trying to make it so is not easy and is not something my parent, for example, can do, even if they want to.
Right now Facebook is under the spotlights, but it's the scapegoat of a whole data business.
I don't know why I should trust twitter with it's tracking buttons everywhere. Why should i trust CDN that centralise queries from a lot of websites. Why should i trust all those services plugged into websites?
My feeling is that it can only be solved and usable by non technical people by having standards for a specific need and that does not allow this level of tracking rather than continue developping "everything" standards that HTTP, HTML, JavaScript and CSS are becoming.
