My issue with iLock was that I had a plugin requiring iLock, and I licensed it.
When the company that hired iLock decided to stop using iLock and not continue forward with the plugin, iLock locked the software I had legally purchased and wouldn't unlock it.
Neither would the company (Oberheim)..

So a certain group hacked it and when I called the online store I bought it from (I think maybe sweetwater, it was a while back) they tipped me off to the hack.
The plugin still works as expected to this day. A few OS later.
So it's not so much iLock I don't like, it's the business model of me taking the chance of using a plugin (I may be relying on for a project) and just randomly having it disabled one day. I was furious when it happened.
