Does not advertise they are paid

There is a Free Demo migration.
The plugin is totally free.

It is not considered ‘free’ if you can only import 10 posts as demo and have to pay for the rest.

Your plugin should be called

“CMS2CMS: Automated (DEMO ONLY) Drupal to WordPress Migration”

Thanks for your comment, mfjtf.
