Free users are helping to debug and improve a new theme faster by using it. It is a two way, give and take relationship.
This is the spirit of WP!!!
I suggest a rule that theme developers who want to be listed in the FREE theme directory, must provide support to free users.
For example, a theme such as SWIFT BASIC listed in the FREE themes directory, in which the developers declare that they don't give support to free users, don't qualify to be in the FREE theme directory, and should be listed in the commercial list. It is misleading us and wasting our time.
