Then one could argue that the software is indeed flawed.
Lets look at it this way ... I work hours upon hours on a drawing, (we have an educational version in the office for training purposes) A noob in training inadvertently opens and saves a block from our block library. (This block is xref'd into thousands of drawings). So, we unknowingly already have a reference to an "educational version" block in all of our drawings. Since all of our plots are done automagically, we wouldn't know they are infected until we plot them. Mind you, we did nothing more than use the licenses consistent with the EULA, (as consistent as you can anyway, forgoing the "cannot profit", as by learning the software you incur a defacto profit), but now we have a serious problem. All of our drawings are now corrupted. Sure, we could attempt to isolate the block(s) affected and remove them from the server, but that will be a monumental task.
I have a serious problem with this scenario as it could conceivably happen. Following the EULA to the letter, yet still falling victim to the dreaded plot stamp.
