Solid performance in WordPress

I’ve had this plugin on WordPress sites for several years.
Whenever there is a major WordPress update, we begin to worry how our plugins will perform with the new version.
The Opinion Stage plugin has never given me problems with compatibility.
Also, I’ve seen reviews that ding this plugin because it isn’t truly free. I prefer paying a reasonable price for things like this because it forms a contractual agreement. Sometimes “Free” can be costly in the end, when the owner of the plugin has no real responsibility toward the users and can add/delete features at will.
