While I understand your point, there's nothing secret about it and it certainly isn't a new thing. It's a question of being able to provide a wide selection of games while still offering provably fair options. We don't believe giving an option harms anyone.
What is the house edge for each game? Are you able to verify it?
Can it be changed?
Would the provider be able to change the game without you knowing?
Do you have access to the source code?
You probably know the answer to most of these questions. As I said, we don't claim that all of our games are provably fair. With third-party games it boils down to whether the user trusts the provider or not. We cannot guarantee most of what you are asking although we try to make sure we don't have games from providers known to run a shady business. As I said, we provide an option and it's up to the user what they choose. There are players who would rather play third-party games simply because of the wide selection.
Now, I didn't give exact answers to your questions because I don't handle the technical side of the site so I am only able to give answers to what I know.
The questions you are asking could be directed to a bunch of sites. As I have said, we're going to remove the seal from the site but again, that cannot be done by me so I've got to wait until it's handled by someone else. I would understand all of these questions if I were claiming all of our games are provably fair but I'm not claiming that so I don't understand the reason behind such a sudden burst of questions.
