This is exactly how users felt when Reddit ran A/B testing on their "feature" that forcibly signed out people on mobile browsers and said they needed to use the Reddit app to sign back in. I saw a crazy long thread of straight backlash about how messed up it was and how they aren't cattle to experiment on and how they didn't consent to that (which they prolly did in the T&C but no one reads that and actually understands what they're agreeing to).

Seeing as they were posting the backlash on Reddit, I'm guessing a lot of people downloaded the app to log in and Reddit said "Big Success!" when they checked the stats.
