Hi,
I don't think moving it to meta is a good solution, don't think its a solution at all.
When the files are on meta people can always use the meta api to get the logo's, we just move it arround.
I don't really think we should care about it, when people use our logo the license will be there to, so no big deal right? Otherwhise we should blacklist the category with the logo's or something like that
