I didn't mean to imply it's a magic number - it's a sweet spot as a cross between power/cost/efficiency. The band wasn't authorized for communications until it was already pretty much spoiled.

It wasn't "authorized for communications".

It was always a junk ISM band, eg used for industrial applications that radiate interference.

Companies can use it on the condition that they accept any interference.
