Well I don't think that ethereum gas fee will exceeds up to $2000 dollars knowing that many people are using their blockchain it will definitely a big problem to them and many people will definitely rally and further boycott them if that will happen.
There is no need for an explicit boycott, Ethereum will take care of itself when it realizes that many of its users are choosing other blockchain network alternatives to meet the needs of every developer or individual.
Hopefully Ethereum 2.0 will be the answer to all the Ethereum community that can provide convenience in making transactions, in the form of low GAS fees that users must pay
