Yes here it goes, the person i helped who wrote DMCA notice about me and took down my project, also put ones files in dropbox i guess, though i think there were other places too. And this was all about these files that person referred to in dropbox, etc, that one claimed to be ones copyright, after one received all help needed. So i don't understand why such hostility of not adding copyright notices to files, it were intelligent and polite at least, when refusing to accept any other importance.
I never took or used any of that code referred by that person, only used it to help that person. I had to upload the built project somewhere, so that person can get it. But it is that wherever you upload it, while they are there, anyone can write DMCA notice about these files, and no matter whether right or wrong that notice is, all your other content there will be immediately taken down. This is what happened, this is the law. I removed all the links to that file anywhere, but couldn't delete it, as some files cannot be deleted in github, and maybe also in other places. But this was not enough for that person who i helped, one still submitted the DMCA notice and took down the single project i had in github,
So i don't understand why such hostility, and why many people here think it's ok.
