First his criticism was „muh $UP isn’t upgradable“... @QuipTalk

Answer2:I explained that, although UP may not be upgradable in the traditional sense, it is a feature that helps to ensure that UP is immutable and secure. I further explained that this is essential for creating trustless and decentralized finance (DeFi) applications, which are becoming increasingly popular. I also noted that UP is built on the Ethereum blockchain, which is a much more secure and reliable platform than BSC or other blockchains that may be hosting „shitcoins“. Ultimately, I hope I was able to convince him that UP is a legitimate and secure platform that is well-suited to the needs of DeFi developers.

He was saying that the claims made by UP were reminiscent of shitcoins that he had seen on BSC
