I think you're a bit paranoid. I don't see a reason why would anyone strip the code.
If someone is actually doing it, it is not worth talking about it and opening a thread in the first place. They'll fuck up themselves wasting their time in illogical activities like that.
Probably you expected more income from your website. Maybe whining about that here may promote your site in some way and you'll get more visitors now.
Good luck with that
