What is an ecosystem?

It also might mean that people who have Photoshop CC and are not familiar with the word (including perhaps a large proportion non-English speakers), will not post here because they see a list of products as "Photoshop Express" "Photoshop Elements" "Photoshop Ecosystem". No I don't have any of them, there must be no support for my product Photoshop CC.

I think there could be a better name.

This was the original announcement

Combining Photoshop & Photoshop Mobile into Photos... - Adobe Support Community - 12180751

There are other threads with discussions on how things will change (in forums restricterd to ACPs) but I have not seen any information on where the name comes from and the reason for it.  You possibly justify it in this forum as it combines Photoshop and Photoshop Mobile (for the iPad) but the Lightroom forum has adobted the same name structure.   The place I worked at for nearly 40 years before retiring has had three different names and is now called 'Dunton Campus'.   The world changes.  What can you do?
