A lot of it has to do with the government regulating people's actions. Its mostly artificial so I doubt that it will stay as a long-time trend. Things will slowly but surely go back to how they were, so online gambling casinos as well as physical casinos should see this as a short setback. I think they would have been better prepared if the governments gave a few months warning before implementing further restrictions and lockdowns. Most people had no idea what the government was going to do next and it really messed up people's businesses
Even with the restriction made by government during the pandemic break that halted almost all gambling activities from taking place except for virtual, many of the casino operators and other gambling games inventors take the bold step forward in reaching out to the people by supplying them with releived materials during the pandemic lockdown while some other remain mute doing nothing, some government as well remain adamant while some shifted ground and will never be forgotten.
The government and alls its vassals and politicians and liars did certainly do a lot of damage during the corona pandemic, thats for sure. But at least we saw their true colors. Whenever there is an emergency, those are the people who will betray us first.
Although having said that gambling casino's game developers and operators did do some things which could be seen as relief for the lock-down-ees but being as pessimistic and suspicious as I am, I would probably say that 99% of that was just good marketing and PR.
Just like a megacorporation wearing blm flags on their social media accounts. Im not buying it.
