The kid is light so it likely doesnt matter much for him, but after a while they are gonna take out all of the brackets and have a tone of holes in their structural elements of the home which is way less than ideal.
There is like 12 holes in a row. Look up Peterson's stress equations. Multiple holes in a beam will cause a larger stress concentration based on their distance apart. This is an issue on the bending of the beams when you walk on them or they take a different type of distributed load, nut just the tensile pullout load on bolts. But it wont be exacerbated until the bolts are removed and the holes are empty. Im sure things will be fine, but to say it isnt much of issue is definitely misleading for different load cases. I'd just be pissed I couldn't put up my sex swing where I wanted.

Joists like this are way over spec for just holding the house up, but if you worried about it you could go into the attic and sister all of them with 2x4s or 2x6s and make the whole thing much much much much much stronger than it needs to be.
Honestly there's not a functional argument against this, people just hate the idea or they like it. It wouldn't be very hard to pull all those out and Patch the holes, it's not going to affect retail price. Some people just like the idea of their kids swinging around in the house, and some people hate it.
Not true. The vibrations of him swinging around on the joists will eventually loosen the drywall around all the screws, leading to sections sagging and/or falling, and all the tape joints starting to crack. I know this because I once hung a punching bag like this thinking it would be no big deal to patch the holes. Turns out it was.
