1. Interoperability appeal

“That’s an awesome project. I’m sure there are many kids that have been gifted LEGO knockoffs that are not compatible with legos from adults that didn’t know any better. A similar “interop” project for those would be great.” — culi

2. Clone‑brick quality concerns

“Almost all (back then, I hear the clone quality is much higher now) were “compatible” but had little to no clutch power, a wall built with some of them would inevitably break at the clone bricks.” — bombcar

3. Legal/trademark hurdles

“Mickey mouse is in the public domain, at last!” — Rygian
“I think they would have a very strong case that using the mouse on a product is likely to confuse consumers about the origin of the product and therefore infringe on their trademark.” — LPisGood
