This comment falls directly into the "things never change" fallacy.
This fallacy can be applied whenever anyone complains about any change anywhere. Picking one sample piece of anecdotal data from another period that can roughly be lined up with some other vague impressions of today does not refute the claim.
I have no strong opinion on overtourism or the effects on it by social media, but I'm willing to listen to people who discuss it without dismissing them.
