What experience are you drawing on for that recommendation? Big companies don't typically negotiate wildly on salary, as it's tied to a leveling system that breaks too many things if your numbers don't fit. They would have to negotiate on levels and make everyone VPs to meet your salary demands, which would cause other problems. So, this might not be the best advice. Acquihirees get a few knobs to turn, but salary is the least turnable.

Is there that much room for a company like Strike to negotiate on salary? I hope they're that entrepreneurial.

For better or worse, I've seen large companies sometimes acquihire (amongst other reasons) as a way to pay up without killing their salary bands.
