iirc Anjoun license cost is something like 40000eur cheaper than curacao who are also alot more strict in what they request of platforms(and attempting to hold them to account). It's no surprise more and more platforms will swap when the online slots market is more competitive than ever
Honestly I did not even notice that they are currently under Anjoun license. Nothing has changed for me, still similar bonus offers 150% + 200 freespins and so on. Withdrawals went quite smooth, took them 3 to 4 days to process each one.
I'm not sure if it's Anjouan but a general impression of mine is that in most of my favourite casinos who also moved over there, the bonus offers have significantly tightened up. Some of them - like King Billy, PlayAmo to name only a couple - offer close to no match deposit bonuses - only FS offers of little to minimal value, while any loyalty rewards or attention from the so-called VIP managers have also taken a turn for the worse. And if I do get anything personalized, it's just some AI *****, asking all kinds of random questions which I'm not going to feed by responding to. Also, most casinos are dropping RTP more and more, KB are even on 92% now on several providers.
