"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".

I think the process begins here http://www.adobe.com/misc/terms.html and the information you are after may be downstream of section 9.5

it doesn't.

all you need to do is download the photoshop sdk, write whatever plug-in you want and offer it for sale. adobe doesn't even have to know about it.

Tony Cooper
I don't know why you keep repeating this point. No one is contesting it. We all know that anyone can write a plug-in for Photoshop or LR and make that plug-in available to anyone without Adobe's knowledge or consent.

What is at question is only what you should call it.
