In reply to Arūnas.
@Otto didn’t you just in this thread said that adding to plugin search results is OK?

If I created a browser extension that would add Drupal to the top of Google search results for ‘CMS’, wouldn’t you see anything wrong with that?

For me, that would be quite an equal thing. And in my mind both of them constitute messing with search.

You say it is not. OK, lets live with that. I created a library that any plugin developer can use to do a Jetpack for their own plugin. I hope someone does, so we can have a test case with a plugin that is not owned by Automattic.

If a lot of them do, the actual search results soon will not be visible in the top fold.
