When I clicked the link... https://www.cnn.com/travel/article/amsterdam-tourist-tax-increase/index.html I have to be honest, I thought it would reveal a big increase, but if I were to look back at some of the places I stayed in the US for Business, this is nothing. In the US I am well aquainted with booking a room and adding sales tax, local option tax, city tax, tourist tax, all totaling much more than the ~12% total this rolls up to. (Try a New Orleans hotel)
The only disappointment I have is that the only solution to over-tourism seems to be taxes and fees, or limited availability. Both favor the people with money (taxes obvious, availability goes to the highest bidder) cutting out the traveler I tend to be.
