Most of the spike in gas prices here was caused by their contract being horrendously un-optimized. If they had done even basic optimization of their contract, gas prices would've been a tiny fraction of what they were, and they would be orders of magnitude smaller if they used ERC-721A. Here's an estimate of what would have happened if they just optimized their damn contract: https://twitter.com/gioperalto/status/1520751524070187010

919.96 ETH would have been saved if they optimized it and stayed on ERC-721, and 39194.05 ETH would have been safed if they also switched ot ERC-721A.

I'm convinced that Yuga is just technically incompetent. All of the people I pay attention to in the crypto space are incensed by everything Yuga is doing here, from the un-optimized contracts to blaming ETH for their own incompetence to their pricing model that excludes everyone except for whales who are already wealthy. The people I follow in the space are small-time independent artists who use NFTs as a way to make a living off their original art, and none of them are happy with Yuga at all.
