It's never been easier to copy and paste your way to riches.
I think you fail to understand that Avalanche actually runs on a novel consensus mechanism that looks nothing like Geth and is investing a great deal in their own network.
I think it's also silly to cry over loss of revenue on public code. IT'S FREE CODE. If you want more revenue for Ethereum and their developed resources, may it's time to consider new licensing for the software they write like what Uniswap is doing with their v3 release. 1 or 2 years proprietary transitioning into public.
