It's completely disgusting. Buy a game for $60, and I should be able to attain everything without signing up on a website or getting a companion app.
I don't mind micro-transactions which they sell throughout to help someone get from A to Z quicker. It's not that intrusive, but going up to a chest and having a website launch or it ask me to download a companion app totally takes me out of the experience.
Not to mention, there are achievements/trophies tied to getting all chests. Just gross.
