Have you seen the latest update from them? I've updated it on my post, the one you quoted.
I think Opensea are letting the third party give em recommendations, they rely upon the third party to solve what should be done to the problem, I guess we can see your #1 and #2 points if it does become one of the recommendations that the third party give or not.
Regarding transparency, on the latest update, they emphasize a lot of the will to improve the transparency within the platforms. Anyway, We'll see how this will play out.
