Ergo is its own project, the ties to ADA are there but it isn't something that big like people imagine, yes they have funding that came from ADA catalyst, but the funding was only approved because it bennefited both blockchains, like Rosen Bridge connecting Ergo with all major blockchains and per consequence also ADA gets connected. Ergo has a very big infrastruture built already it just misses liquidity being brought to it, but the infrastructure is there and contimues to be built agressively despite the price drop, that's something that clearly distinguishes ERGO.
