This is what I was afraid of. Your plugin provides free access to my assets for free to everyone. I'd love to say yes just keep them in there, but it is threatening my survival as an incredibly poor artist. Since it is open source, I guess there is no way to restrict access to the assets themselves, so I will kindly ask that you remove them from there asap. I'm sorry.
Thank you for being open and honest about this. I really appreciate it.
