Okay, how this changes the core argument? The videos were not taken down briefly because they did not comply with the Turkish law that protects Ataturk from defamation but for the claim that they violated someones commercial interests.

As the claim you made about copyright being used to take down a video was completely false, how did it contribute to anything?

The video wasn't taken down over commercial interests. They were taken down because some old law prohibited insults at representatives of other nations, with whom Germany has diplomatic relationships.
