What is the big deal? Binance is a popular crypto exchange. Them having links to a particular crypto casino or betting site doesn't automatically make that site a popular crypto casino or betting site.
Personally, I have never heard of Bplay before and am not really interested in checking it out just because Binance is affiliated with it. Bplay needs to advertise their site here properly in order to attract gamblers.
However, if Binance offered some great offers on Bplay, that would help attract way more gamblers.
The only big deal here is the feature that you can directly sign in on the casino using your binance account. Its a bit risky since you will input your binance details and you will only do that if the site was trusted. In opinion, It's too risky to connect exchange account to a casino because they are different industry and purpose. Binance is also not liable in case the casino turns to be a fraud so better safe than sorry later.
Real talk. Is there anybody here that will connect there exchange account on any gambling casino?? You will be tempted to gamble more if you do this.
I agree with TGD, I would never connect my Binance account to a gambling site. My earning would directly go to dice or blackjack ahahah
But after a quick view online it seems legit. But it doesn't mean anything as people can simply buy exposure (or an employee) to publish things.
I definitely have some doubts, first, the domain name was bought, again, in 2019 and since then the only "advertising" is on Binance blog and some Twitter posts. I didn't see any Press release on major or even minor crypto-related newspapers.
Back in 2011 the domain was a Russian thing (not quite sure what is it, you can check more here

Okay maybe the name was short and nice but still why if they are partner with such colossus not doing good marketing with some promotion, exposure on media and so on? I would say is still at the beginning. Bplay token?? never heard and found anything about it... still need more time to investigate. If I find anything I will definitely share.
