That is true but only on one condition and that is if the add-on you've installed contains the code which is directly taken from the paid resource developer without their permission.If your website is using a plug-in designed by a developer that violated intellectual property law, there's a good chance you'll be forced to remove the plug-in from your website.
such as the hijack of waindigo install function code in almost every add on (for which ******* apologised)?
I dare say this will be re-factored and updates released.
Even re written there are only so many ways to do it and it wont be that disimilar in the future.
It is blatantly obvious that it is a (nearly) exact copy from Jon's add-ons. It has the exact same phrasing in the error messages, if ******* would have rewritten it they would have been in broken english, guaranteed. The point is that he used Jon's code without his permission.
The actual point is Jon already accepted the apology and the previous poster was taking it to things it didn't have anything to do with such as uninstallation tracking code. I was setting the record straight and the quoted portion takes it back out of context.
