Sadly, some of those casino
does entitled to be questioned and "demanded" to reveal their basis of their accusation --not their strategy-- because, like
Little Mouse said, some ill-intentioned casino use "you agree to our ToS" and alike to get away from their wrongful accusation. One good example is err... a casino with fruit-slash-vegetable name attached to it that I recently attended, they finally tried to hide behind NDA to settle their issue with a customer raising their dispute here because --I can only assume-- they can't prove that their reason of banning is valid. And this outcome were achieved because the community requested a proof of their counter-accusation against the user.
Another notorious case is err... that site with scale and two dice for their logo, where upon a long and hard cat-and-mouse, they suddenly withdrawn their decision
and "compensate" the user for the inconvenience. This too achieved because they were asked for proof of their claim and unable to provide, the situation would probably ends differently with the victim losing even more if the forum didn't assist the issue.
Although, there also cases where the accuser are clearly the wrong side here, yet had the audacity to demand more and more evidences although the representative of the casino had provided enough.

Out of curiosity, why are some of the biggest names of the crypto gambling industry finding themselves in such, and you say they didn't pay you... If you have the evidence you can open a scam accusation against them to try get this resolved.
It's... OP is being satirical, in response to the blooming of recent cases where people claimed being scammed by trusted casino like sportsbet or stake. OP is not actually currently being scammed by them
