As you can see in my "public profile" I'm an engineer, I have a CPL/IR license but no TR because actually I'm still searching for work as a pilot. So unfortunately I do not have a CPT to ask for.
Since I am very passionate about airplanes, company airlines and all that is involved in this environment, thanks to a friend of mine (with which I shared the ATPL course) that actually was more lucky than me in finding a company to work with, I had access to interesting documentation to study and to grow up my knoledge about this work.
Maybe your answer might not have seemed so kind.
I think that sharing the knowledge is a good thing between people with passion for something but anyway it is not an obligation.
So I'm sorry if I disturbed someone. I think I did not violate any forum rule asking about the above argument.
But my intention now is not to open a debate about the above, but simply to learn more about something that I found interesting.
Have a good day
