I think the same thing will happen to this site in the near future as to their previous site:
https://freedoge.co.in/If I am not mistaken, they decided to shut down freedogecoin due to massive cheating and abuse by some users. In other words, it was not feasible for them to spend resources on that site.
As for the freebitcoin website, even if it shuts down, it will clearly not be the same as when freedogecoin shut down.
There's a thread discuss about that before
https://bitcointalk.org/index.php?topic=5180819.0Also I think they can't handle the cheating issue anymore and they lose lots of money with it that's why they just choose to shut it down then focus on their freebitco.in.
I doubt their casino is generating profit compared before due to competition while the passive income from players is continuous.
Their silence and delay of improvement might be a signal that they are struggling already to maintain the profit sharing to players.
If they are still earning or their casino is profitable for sure that people won't experience those disturbing issue.
But since there's lots of troubles already shown up then with that maybe your assumptions that there platform is not generating well. Also I'm not surprised about this since if we could see here there's lots of casinos launching their business and maybe they are affected on that situation.
