What does “crush an etf” even mean? Crush them personally?

As many other said, it would be best to have more context. I am neutral on Saylor, not simping, but I don’t see the logic behind that position either

- is he afraid ETF sponsors will decide development?

- is he afraid of any development?

- is he afraid of a specific development which was to be sponsored?

- the crushing part is weird, crushing “how exactly”?
