I read the article and it's pretty flaky. Not much substance and makes a number of sensationalized comments.
Obviously, the MGA works and for once we have properly licensed casinos in the EU. They can handle player issues, and the casinos operating out of there are on average pretty well vetted. So international businesses are taxed 3%? That's their sovereign right to do so. I wish I was paying only 3% tax.
You do realize that if the casinos that you so happily play were to be taxed 35-45% it would kill the business - you'd probably never see another bonus again.
To compare Malta to Panama is a joke. People doing so have probably never set foot in either country. The article should have been named "Malta: 3% taxes for International Businesses and the EU doesn't like it."
Well, duh. Low taxes, it's in the EU, it's legal, and it's properly vetted. Where else are you going to go?
