If it matters, Docker is learning
I understood you, but this is a community forum and I am a community member, so I am thinking as such 
and trying to learn from your opinions which might point out something that would affect others, maybe even me so I can do some research to find out if it will happen. You can see from my words that you emphasized that “I believe”, but I may be wrong. Docker could have released the initial scanning feature without telling us what is behind it (let’s imagine the contract would have allowed it) and change it later. From my point of view the most important thing is to get the same feature. If I get that, I don’t care what is behind it. Snyk has a well-known name and we knew very well that it was behind the vulnerability scanning and this is what changes how we judge the change of the feature. If Snyk changes anything in its own product, the most of us probably think it is an improvement.
So I get that it was not communicated well, but we can’t change that. We can only ask for more information and clarification which you did here! And all I can do is offer my help to get more, but it is easier if I have a specific question to ask or search for. Of course I understand if you dont want to “think more about Docker” on your busy days. In that case, I just which you have a nice day and thank you for sharing your opinion and questions in a civilized way!
