In order to use their service, you must provide them with all kinds of personal details so they can forward it to the authorities and to also sell it to other entities.
If you refuse, you can't use their service.
If they refuse, the government will shut them down.
All these "bitcoin" companies that snitch on their clients are spineless and immoral but they try to hide this fact by providing a "great" service.
Unfortunately, all the plebs that use their services are either morons or gung ho.
