To combat people making copies of a violet-eyed drow renegade, they made all drow renegades violet-eyed? That's the exact opposite of discouraging drizzt clones.
It's that or have a legion of drow that directly contradict the canon.
...What? Like I said. This does absolutely nothing to discourage Drizzt clones. If anything, it makes any drow renegade significantly more Drizzt-like, because Drizzt had violet eyes. It doesn't say 'you can't be a drow renegade any more' it's 'you can be a drow renegade, you just have to have violet eyes like Drizzt now'. And setting aside the fact that there has canonically been large numbers of organized non-lolth worshipping drow for irl decades at this point, the eye color thing itself is a break from prior canon.
