There are two categories:

1. Suggestions to use other paid microsoft products like onedrive and office 365. Apple does something similar with icloud, apple music, but microsoft is more annoying about it because they'll pop up those suggestions all over the place whereas apple will typically put this in more logical places. Overall this makes sense though, and sometimes I've used this to quickly get to one of these services (because I use all of them anyway).

2. Promoted apps from the windows store that they push in the start menu. I find this quite annoying, and I'm not aware of another OS that does it. I'm also doubtful it actually makes them that much money. It probably harms their bottom line more than it helps, which is why nobody else is doing it.
