I get what you mean. But the thing about complete bootlegs of prexisting sets is that you usually get out what you put in.
If they're much cheaper, you're probably gonna wind up with cheaper plastic. Duly deserved. Common sense dictates that if a price is too good to be true, it probably is, and that's to say nothing of blatantly obvious copyright-avoiding names and labels. They're easily avoided. If you actively want the cheaper price, you get the cheaper quality. If you want the premium price, you get the premium quality. Yadda yadda yadda.
However, in those rare situations where the bootleg is on par with the set it's mimicking, or even surpasses it, then that's just shortsighted business on Lego's part. That's beating them at their own game, and the smart consumer should seize the opportunity for a better product. Hardcore brand loyalty breeds monopoly. If you value getting the best experience, then support the better product.
This has been a thing with Transformers for years (which is why I brought them up earlier). Companies like Kubianbao and Weijang have made KOs of bots that either match the quality of the original toys, or surpass them with bigger sizes and new features. It's only smart consumerism to get their products if they're more bang for your buck, and if Hasbro sees this as a threat, they should up their own standards to win over customers.
When two companies compete to make the better product, the only definitive winner is the consumer. That's my two cents.
Someone let me know if I'm getting too political here.
