Creating or providing a tool and using a tool are not the same action. Likewise, since there are legal fair use scenarios of copyrighted materials (short clips, criticism, satire, academic, etc) so even using the tool isn't inherently against the law and the person creating or providing the tools can't know and legally doesn't need to know the end user's intentions.
Copyright lawyers working for the highest profile abuser of copyrights absolutely know the very basics of copyright law and are therefore acting in bad faith.
