All of these are about sponsored content. AFAIK in the current model of sponsored content have to inlude some tracking as they need to keep track of how many click goes through, and charge their client according to that.

I kind of wish there would be non-tracking based ads, like burned in mid-roll ads on youtube: Just give a shout out and collect money. But it is pertty hard to convince others to switch to that model without solid data.

Finally, everything they mentioned are sponsored content and pocket, both can be turned off with one click. I call that a win in the distopian modern internet. And obviously there are more privacy oriented fork that strips these tracking content by default.
