Agree!

There are many ways to educate users. Jetpack already has admin notification, dashboard widgets, a dedicated admin menu with an admin page. That’s enough for it to show helpful info to users.

What if other plugins do the same?

And what if other plugins do not only for the plugin search result page, but other admin pages? Note that the way Jetpack does is very dodgy – via JavaScript!

FYI: I remember a rule for all themes on .org that they can only add one button in the Customizer with the “Pro section” from Justin Tadlock. No JS-hijacking is allowed, no other ads/promotions/links are allowed! Why can Jetpack?
