you still custimise your feed to large extent by following stuff.
I’m not that familiar with the latest versions of the three I listed, but I’ve seen quite a few complaints on Reddit recently who seems to be pushing irrelevant content just for rage bait.
Also the things you mentioned about tracking are there on Twitter too:
Twitter’s privacy policy states they use the information collected to: “improve and personalise our products and services so that you have a better experience on Twitter, including by showing you more relevant content and ads, suggesting people and topics to follow, enabling and helping you discover affiliates, third-party apps, and services.”
It’s important to note that opting out of Twitter’s interest-based ads doesn’t necessarily mean you won’t see targeted advertising. For example, you may still see ads which are based on information such as what you Tweet, who you follow and the links you click on Twitter.
Often while browsing, if Twitter recognises that you’re interacting with something repeatedly, they will offer for you to follow that particular topic – which can be anything from celebrities to sports teams.
Nice one ha ha
