Google deliberately intertwine all their stuff so that they can pull junk like this. Maybe there's one product you really want; and probably that product was easily accessible and unencumbered when it was new. But now if you want to keep using it, you gotta let Google have their way with you - body and mind, you must submit or they'll take away the 'gift' that they originally gave freely.

Of course we shouldn't submit to threats like that. Giving in to that just makes them stronger, and us weaker - and so it gets worse.
