Ethereum is the only non-ponzi-scheme in crypto. Most of the complaints about ETH's tokenomics etc. essentially boil down to the fact that Ethereum is not designed as a ponzi scheme. This is why even people who hate Ethereum like Ripple ultimately also end up building on Ethereum and even people who Ethereum leadership despises like Trump build on Ethereum. You can be Vitalik's personal enemy and it's not going to matter one iota.
