I really hope the people appreciate the support you give to your freebies. If they are half the quality of your sold products, they would still be great. 

The discussion about people aren't gratefull enough when it comes to freebies isn't new. There are some people who pulled their freebies because they got complains about them, or felt that they did not get enough positive and thankfull feedback.
