Edit: Seems the below statement was factually incorrect. Oops!
It’s a very obnoxious and heavy-handed approach to anti-piracy measures. It slows down games, kills framerates, gives users a whole host of other performance issues, and just makes the experience worse overall. It’s a product that doesn’t even seem to care to improve, because they make their money from publishers, not the people who buy and play the game. Many people hate it, and I believe it’s absolutely justified.
