I'm sad to say this, but these recent decisions of Invision Power to make it harder for their customers just to prevent Piracy has given Xenforo a complete monopoly in paid forum software.
Vbulleting and IPS are running further and further behind focusing on the wrong things.
For example my one big issue before 4.5 was IPS inability to create small thumbnails for every image attachment automatically like Xenforo does. you could argue that it does if you change the image size but you will never be able to choose between a tiny or large image, you will be stuck with small images then. @onlyME is a great developer and one of the biggest reasons why I stayed on IPS so long, however his addon : https://invisioncommunity.com/files/file/7436-bim-topic-thumbnail/ BIM Topic Thumbnail needs to create his own thumbnails in order for your website to load in a couple of seconds.
Compare that to xenforo where the developer just can use the thumbnails from the inherent system. @onlyME had to make one himself.
In my opinion something like that should be a priority including a new text editor that apparently you'll add in 4.6, because the current editor takes a couple of seconds to load.
You have lost a customer with me, I and many others don't like a closed system where the creator tells you how to do things, and you can't do it any other way.
In the long run you will financially lose more from this than piracy ever will, this includes 3rd party developers.
I'm not defending piracy at all here, just your customer treatment in limiting their freedoms the way they use your products. I probably spend 1000+ dollars on custom development, plugins, themes, and the core products during my membership here.
I don't want to be rude or disrespectful just giving my honest opinion, I suspect a lot of other customers feel the same way.
