Wikipedia is an encyclopedia, the only one left, and it gets to define what an encyclopedia will be to everyone from this day forward. Excuses for my it must limit itself are inane.
He didn't have to tell anyone "Get as much stuff out of Wikipedia as possible so I can make money off it", that was just going to happen institutionally as a result of his clout and conflict of interest. People would obey in advance, and people without enough radar to realize they should would lose out against those who did.
I would find an encyclopedia with exactly zero article about any individual biography far more ambitious than one that cover only some, provided it would explain everything in term of structuralist perspective and consider names of actual people involved as relevant as the names of cells in a macrosized living form.
Or indeed the other way around, covering every single individual with an equal level of details, should it be done with first hand done investigation.
The middle ground that let enter only articles about people whose personal information passed the selection bias of other institutions is the lowest ambition of them all.
But if the pop culture lore has insane depth then it’s probably valuable enough to keep, yeah? If it has a few limited snippets and very few people writing about it as sources, then it’s a lot more questionable
There is absolutely no reason whatsoever for Mr. Tik-tok from Oz to have his own Wikipedia page. He's less notable than, say, Knight Artorias, and I don't think anyone in their right mind would argue Knight Artorias deserves one.

A minor fun fact: Playing Tik-Tok on stage was one the early roles of James C. Morton, who appeared in a truly ridiculous number of comedy films from the 20s thorugh the 40s alongside the Three Stooges, Laurel and Hardy, Charlie Chaplin, and others.
Now there can be other relevant limitations, like physical constraints such as how much data storage is available, or social concerns like not divulging the physical address when some threats and hurts are very plausible consequences.
