On mobile ? Not really. Their website is mobile cancer, and their app is barely better. I'm impressed at how bad it is, and it's not even about "pushing more ads" but "controlling what people see". That's also why they've removed r/all.
r/popular already existed before, and this is different, it's the same idea as facebook, instagram, twitter ... It's a curated feed not in an order or same weight feed. In other words, it's used or can and will be used to push whatever.
