"This is why you see so many popups and banners on mobile websites
that try to get you to download apps. It is also why so many mobile
websites are broken."
Huh, is that surprising? They break their mobile sites and expect people to still use them more than apps? This is self fulfulling: if you make a sucky website, people will NOT use it. Make a wonderful mobile site and people will not care about your apps.
The problem that i see is that once big 'popular' readers are gone, it's possible that publishers decide that RSS is a feature not worth having/maintaining. That's a choice that has been made already by platforms like Twitter and such.
A lot of new (more recent) blog platforms also did not prioritize RSS.
So, as much as I agree with the statement, I'm worried that in the end, we'll all lose.
Finally, Feedly's strategy here is probably one of the best way to make sure that publishers stop puvblising RSS feeds.
