While the folks like Bourdain did romanticize tourism, and TV shows are known to regularly kill businesses that don't know how to manage the increase in customers, they did at least project the proper attitude of embracing the differences in other cultures when they traveled to places.

The current issues with tourism are significantly more to do with "influencers" and social media. Many places are overrun by people that are just there to get their photos and have zero interest in engaging with the culture or treating locals with respect.

Its shocking how different some places have gotten due to "influencers". Last year I was in Kuala Lumpur for a few days and took the person I was with to a bunch of the places I had visited when I was there a decade ago. It struck me when walking around a couple places that there are photos I took during my first trip that would simply be impossible to get today because of the number of people in the way.
