Who cares? A lot of people, the people who've given the issue some thought and don't like corporate interest pooping on them. You should have more self respect. Here's your path to englightenment:
What Ubisoft is doing is bad because it breaks the illusion of the game experience. A piece of art is supposed to draw you into the illusion of being a real place, like a book or a movie. Being constantly reminded about real world stuff that is outside the game is a deliberate act of sabotage to the world they have tried to create. That's one reason why it's bad. You wouldn't get Martin Scorsese appearing 20 minutes into his movie to remind you about a web page that contains some background info on the characters.
Another reason is it's inconvenient. Instead of being able to do the game stuff in the game, you have to leave the game to do stuff for the game. That's just plain old bad design.
Third reason it's bad: There's absolutely no point in any of this. There is no benefit to the consumer/player at all. It's purely so Ubisoft Corporate can get your details and attempt to sell you more ethically bankrupt crap. If these tactics work, Ubisoft will push harder and harder until entire areas of the map won't be unlocked until you launch some trash on your phone and give them your home address.
And if you still don't care, fine. But it's YOU that doesn't care, lots of other people do.
