You don't have to hide content.

Some people do it and it annoys. But it can also be simple things like: Big screens see 2 1/2 screen wide tables across, small screens so the tables under each other. No hidden info either way, just scaled well.

I think good responsive website is the ideal end state. I do not want an app for every single thing I visit. A few important things sure. If stripe was my main activity, sure! But if I am just using it to watch my monthly sales number... rather have a good mobile website.

You are the first person I've ever heard say that they hate responsive websites. Unless you're playing around with your window size, you wouldn't even notice if they adding responsive features to the dashboard. Sounds like you just hate poorly done websites.

Is a site truly responsive if it delivers a lesser experience on mobile, even if it does happen to change the layout so that the experience it delivers, regardless of the lack of content, does work on mobile?
