once again, there is no approval necessary to write and sell a photoshop plug-in and call it that, which is what a lot of companies do.

To paraphrase one of your favorite terms: no one has said that any approval is required to write a plug-in to used with an Adobe product.

Only to "use with" Photoshop:

"they can approve vendors as suppliers of plugins for Photoshop. The plugins on that page are evidently plugins that Adobe has approved for use with Photoshop."

Only - you have never been able to provide any support for the approval process from Adobe for plugins to be "used with" Photoshop.

You pointed to a process wherein Adobe approves to include the plug-in on their market place (titled "Photoshop Plug-ins" while none are authored by Adobe), but that failed to provide support for the claim that they approve the plugins "for use with Photoshop".
