I am not getting your point here, Bitz supports VPN connection, they have one obviously but you now saying that people should make sure they are gambling from country they support is confusing.
Everyone that are from supported countries won't have any reasons to use VPN in the first place, it's always those who are restricted or from unsupported location will want to use VPN connection.
Am I wrong about this? Because I don't see any reasons to use VPN unless my location isn't supported, my advice is use casinos that supports your location, if it's not supporting your location better find another, to avoid stories later.
A gambling site may allow people from a country but the game provider may not allow the people from the country. VPN can help in that situation.
There are some people that gamble from countries that are not restricted but using VPN. Some people can be afraid, but with Bitz VPN, they will not be afraid because the VPN is controlled by Bitz.
I get your part but it's on the casino to still allow such in the end not the provider, the casinos aren't in the care of game providers I believe so it's on the casino team to give one a go ahead call or tell them to not use VPN.
Still I wouldn't trust a online casino that tells me to not worry and proceed to using VPN, because if I hit something massive along the line they can deny that they ever told me to use VPN connection.
I can only try such with a very big casino like Stake, I will even advice people to take screenshot when a casino representative tells them to use VPN just in case, they can one day denied that fact.
