This is an interesting observation. I hadn't noticed this dynamic before; thanks for sharing.

The current differences in attitudes between mobile and non-mobile apps is pretty interesting.

If you visit Reddit or Twitter from a browser that's running on a mobile OS then they make it extremely clear that they would prefer that you use a dedicated app. When visiting from a non-mobile OS not only do you not see such messages, but a dedicated app doesn't even exist.

In one place the browser is good enough to be the only option, in the other it's so inferior that they will bully and harass you until you stop using it.
