I understand not everything can be free, but I do not agree with the way this move to fee service was done.

To just make the service "not work" anymore, causing the site to display a blank page, is in very poor form.

This happened to a customer's site, I will tell her why it has happened, and if she chooses to pay, that is her prerogative, but I do not like the idea of supporting these kinds of practices.

Perhaps it's because of zen cart's limitations, but this "Fee service" is not even explained in the download page here on zen cart!

I can understand if a newer and better fee based service was developed, and then support for the older free one was discontinued, but to just cut people off with no explanation really sucks. I don't think I've seen anything like it before.

I think it's ironic that your site tagline is "You never know what you will find". In light of these changes, that really becomes quite a negative statement. Great, what will happen next?
