But this story raises some more serious questions. When I sign up in a casino or in any other service, this should mean that I trust this company to hold my data, and the part issuing the license.
Does it stipulate in the TOS that private data of the registered users can be transferred to the new owner if the original owner voluntarily changes ownership? (Not confiscation by authorities). What if I, as a user, do not want to share my data with the new company for any reason? Do I have the right for objection by any mean?
All that is covered in the privacy policy which is why I say it's very important to read and understand it before you sign up. Once you share your information with any of these platforms. Consider it already unsafe even when they promise that they will safely protect your data
Here are bits of the privacy policy
We may disclose your personal information to third parties:
In the event that we sell or buy any business or assets, in which case we may disclose your personal data to the prospective seller or buyer of such business or assets.
If Royal Stars Casino or substantially all of its assets are acquired by a third party, in which case personal data held by it about its customers will be one of the transferred assets.
Here are your rights. You can actually start by closing/deleting your account with the platform.
