Browsing history!? Well, if I actually notice that it's there, that would be a no-go.
Actually, now that I think about it, that could be OK, but I'm going to need assurances that the data is anonymized. By that, I don't mean just writing it down on the agreement, I mean paying some third party to monitor the data going back to make sure it's anonymous. When the game gets less popular and paying somebody to monitor the data is no longer financially sane, they have to remove the monitoring. If data becomes not anonymous, the third party tells the developers AND the gaming community (via Steam announcements and other platform equivalents).
P.S. Those agreements can sometimes be useful to refuse. Metal Gear Solid 5: Phantom Pain has an online component that I didn't want any part of. By refusing the online interactions agreement, I was able to completely turn off all the online pieces! Options are good (when taken in moderation)!
