These are considered illegal now and in my place, there are really those physical betting places for online cockfighting.
Physical bets on the cockpit arena itself are legal and 100% operational. It's safe to bet there.
Only the online "sabong" is halted but cannot be considered illegal for now as it was just suspended until further notice.
If you see online sabong still streamed, then it was running under the shadows and not held in the official arena. But I'm sure it's just a small market like the online color games, online bingo, online "perya" games, etc.
Operators are still there and willing to gamble with the risk, knowing that many people will continue to patronize the business. In their part, since the permits are suspended, they are facilitating without any implemented taxes. It's worth the risk if there's a big money involve, like the examples that you mentioned, those online perya games are considered illegal but people continue to play. Though not in the mainstream anymore if dealing with online Sabong.
There are gamblers and bankers who continue to regulate. Even the suspension from the government has already been announced.
They are willing to cater to those who are also willing to gamble and risk their money.
