Yes, this is the issue with Tidy. What you can do is create a rewriter that can change < into < at publish time, but it will still stay as gibberish in component as content. Also, it might interfere with your html on a page.

Also, have you tried publishing it? How is it seen on a page? < > characters are automatically changed to their encoded values so that browsers can differentiate them from opening and closing tags.
