Adobe has taken every extension feature i’ve created.

I have three extensions in adobe exchange marketplace and all three have been copied into built in features and I feel cheated. I am not an adobe competitor and I felt like I was adding value to their products, but now I feel I've been taken advantage of. 

With so many feature requests that go ignored, I found it suspicious that all three of my extensions happen to be added in a short period of time when they were features not even requested by the community. 

furthermore, why shoud any of us continue to develop for adobe with no protection? I feel they see community built extensions as proof of concept before they work on similar features inhouse. When my first extension was copied I was like "okay", but then two more got copied in the same update! 

One is a paid extension in which not only did I put  a lot of work into, but I've spent a lot of time providing support to my users in areas I have no control over like creative cloud installation issues. 

Adobe is a very profitable company and yet supply no support to their users and instead they rely on communities to answer questions and help others, but now they also take from developers.
