i completely understand that.
But you should know better than to ask a user to pay you $100 to add something that benefits everyone using it. Thats unethical. You should only and clearly state that the plugin will not be updated. Or, make a premium version that users can pay a small fee to purchase.
I guess im saying if you are going to put your “Free” plugins up for others to use, expect them to ask you for support if there is an issue.
You will see that there are a lot of developers that have no problem improving their plugins. Not saying you have to do that, you absolutely don’t. But web developers depend highly on the contributions of those amazing developers.
Either way, thanks.
