Reddit had/has a plan to block mobile browsers in favor of their app

I genuinely don't get it. I fully understand pushing users towards the app. But there is going to be a portion of users who will never install your app. So at some point, you are just pissing off those users by making your product worse and worse, and they're never going to install the app anyway. I'd rather the utterly atrocious experience of browsing the laggy desktop site on my phone.
