The specialist diagnosed his tonsil enlargement as grade 3 (4 maximum) and recommended tonsillectomy and adenoidectomy. This is recommended in grade 3s with his symptoms; strongly advised in grade 4s. But the specialist gave them thorough context that led them to go against his advice. Children go through 2 growth spurts of the neck around ages 5-7 and ages 10-12. After these growth spurts the ratio of tonsil mass to neck cavity decreases, giving even large tonsils more room -- possibly enough to no longer require surgery.
They pursued simpler treatments like saline sprays before bed to make nose breathing easier, which greatly reduced snoring. Developmental delays were caught up, and now at 6 years old they are glad they avoided the surgery, though admit it wasn't necessarily bad advice and were prepared to reconsider it if no progress was shown in 6 or so months.

Circumcision for hygiene is a bit like shaving your whole head so you don't need to use shampoo(Edit: with the difference that hair can actually grow back and doesn't have countless sensitive nerve endings).
Placebo does not just mean an effect that is questionable or might not be present.
But there is 0 evidence of placebos having actual positive effects aprt from the first one about subjective symptoms.
A placebo never stops a virus infection, although you might feel like it helps a bit.

Sadly, tonsillectomies on adults are actually quite complex and dangerous, but as a chronic tonsil sufferer, i assure you, removing them would not be a placebo. And every year, i have a week when i check hourly whether Laser tonsil ablation is available and approved in USA yet.
Luckily, as a child I had my tonsils removed. It was just something almost everyone did. After that I had only an occasional sore throat. In contrast friends who still had their tonsils had serious illness, visits to the hospital, weeks out of school and parents who constantly worried.
So as far as tonsils are concerned my feeling are "Good riddance!"
