The OP's point wasn't about ads but about the algorithmic newsfeed. The newsfeed is designed and optimized to make you like scrolling. So, yes people do like to scrolling but hate it when they realize that it might take you 20 minutes instead of 2 minutes to get to your best friends new baby announcement. Sure, ads contribute to that frustration, but they aren't the sole reason for it.
The key distinction is that news feeds' customers are advertisers, not the audience. News feeds were not built to maximize the audience's experience: it's an inherently consumer-adversarial technology.
