Netherlands is one of the most challenging markets to work on, and most big players rather opt out of it than pay all the hefty fines that the gov is giving out in case they catch you. The few big local operators that are there basically have a monopoly under the current Kansspelautoriteit laws, and remote gambling operators are still excluded from most frameworks = but the gov promised that they will introduce it soon.
For a very long time, the Dutch government had a monopoly on gambling with the State casino and State lottery. Later, they allowed "competition", but they had to send 50% of their revenue to "charities" (this was recently reduced to 40%). They also use agressive marketing with massive advertising, by phone, targeted post, TV and more. The State lottery is the only one in which winners are exempted from paying tax. There have also been lawsuits (which lead to compensation for players) because the State lottery was misleading players by advertising with prices that fell on tickets that didn't get sold.
Online casino taxes can be even trickier, I've read cases in which every winning was taxed, and losses were not deductible. So basically wagering becomes very expensive.
As a Dutch tax payer, I can't say I feel "protected" by the current Dutch gambling laws. It's all about the money for government.
If you open up a few of the MGA and Curacao licensed casinos you'll see that no one has your language available and the country is blocked on IP level.
That's ironic, since Curacao is part of the Kingdom of the Netherlands.
