How on earth does buying Wiz force other developers to move? I think the tinfoil is too tight.
Large enterprises don't sign the stock terms and conditions that would enable this, most do or should have legal teams redlining contracts around how cloud data is accessed and used by vendors. Maybe Wiz is so good they would agree to it, but it would get challenged and negotiated during the sales cycle.
That's probably cos I am far away from this space.
