ETH's supply growth without the burn maxes out at about 2% annually, in the case of almost the entire supply being staked. That's still less than major fiat currencies. Its current growth rate is less than Bitcoin's.
For the burn to be so extreme, the demand for transaction space would have to be much greater than the space available. Since they're also making large improvements to scaling, with the roadmap going to millions of transactions per second and the hardest parts already done, that also seems unlikely.
As for the infamous fork, that happened in Ethereum's first year and it didn't change the ETH supply. Nothing like it has happened in the nine years since. Bitcoin forked when it was eighteen months old, and that actually did change the Bitcoin supply.
