maybe because it is important for devs to analyze the player's behaviour? Not the first and wont be the last devs who do that.

It's even used inside of steam

i do belive they have to add an agreement to that, adding such features without telling enyone would be illegal as i have not accepted such agreement enywhere.

*Adding a disable feature for tracking like Generation Zero has should be an option.

Depends on what information they're collecting. If it's data that could be used to identify you in any way then yes. If they're just gathering key clicks per second, number of times you jumped, how long it took you to make item X etc they have no such obligation.

Analytics can cover a lot of things and it makes perfect sense to use Google's analytics engine rather than writing one themselves.

EU laws are pretty strict, I'd be really shocked if they were breaching them.
