I think what you're describing is WeWork and Theranos. So, sure, they happen, but they get found out eventually, and in both cases, they were found out before they went public.
Looking at the list of "Former Unicorns" on this page [1], I can't see many that fit your description. Sure, there's a handful, inevitably, but it's far from the norm. Most of them have grown into real businesses making real revenues. And sure, some of them may be still making losses but that's a valid strategy where there is still growth potential in the market.
Granted, Uber is a big question mark; it remains to be seen whether they will ever turn out to be profitable. But everyone knows what the strategy and the bet is, it's just a matter of waiting to see if the bet pays off. But no serious commentator could dispute that Uber's founders and present executives are talented people, building a company of substance.
So, if the claim is that it's commonplace for unskilled/disingenuous founders to build huge, successful-seeming companies just through huge sums of VC money being pumped in, then exiting and fleeing the scene before they get found out - there don't seem to be many real examples of that happening as far as I can tell.
