If said ETF did their homework properly, their handling of a fork should be described in detail in their prospectus.
Not that I would ever buy a BTC ETF since it precisely negates what I believe Bitcoin to be useful for, but if I had to, I'd pick the one that would convert the forked coins back to BTC immediately after the fork.
If enough ETFs actually promise to apply this policy in their statutes, that would make it quite a hump to get over for a would-be forker, knowing the immediate price hit the forked coin would take because of the ETF immediately dumping it.
Now, that is a very interesting question.
