So I'm confused. I warned you I could not understand very technical things, and plus my poor English. I'm just an OpenSource user. So, to make it simple to my not a developer mind, I divide the possibilities into two groups:

1) It is easy to analyze, study, understand, copy, reverse engineer the closed software/formats. If this is so, if the OpenSource has poor compatibility with closed software, then it is because OpenSource faults. Do not blame the propietary software.

2) No, it is not easy to analyze, study, understand, copy, reverse engineer the closed software/formats. Then the closed software imposes limits that make the OpenSource be at some disadvantage against closed software, as I had initially pointed.

Sorry to divide things into these two basic groups, but I need to know which of these two basic options is closer to reality.

Edit:
Now I see that my previous question can be misunderstood. I literally did not want to say "you are saying that....". Was a question "are you saying that....?". Better I should have asked: "For what you said before, then we should......?"

YAFU, you are oversimplifying things I cannot pick between these two options: I'd be lying.
