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.
