Didn't WPE release some of the most popular WP plugins of all time? Advanced Form Fields etc? How is that not contributing to the ecosystem?

I'm not sure it's logically consistent to attack the phrase "rent seeeking" as unclear, then apply it anyway (?!) but muddle the word "contributing" in turn, to reach pre-desired conclusions about which party is at fault. You'll have to clarify for me what branch of neo-classical economics is concerned with assigning fault. Seems entirely removed from economics for me.

More broadly, we're not discussing any of this in the context of "contemporary classical economics" (ie right of centre economics), so I have no idea why you think we'd agree on using those definitions, or why those definitions have pride of place over any others.
