Somebody who has literally 140 discrete wifi based IOT devices yet has put them all on the same channel and is further using half duplex mesh repeaters also on the same single channel, is probably the sort of technology early adopter/enthusiast who
thinks they know what they are doing, with a high degree of confidence, but actually doesn't.
I have to admit I am biased by doing some microwave band rf engineering stuff professionally, so my perspective on it is perhaps a bit more critical than others. You could say I've seen how the sausage is made...
