In order for something to be fraud there has to be deception. This was never the case with WeWork.
Now obviously, in this case, it was too blatant and stunk bad enough that even retail investors shied away.
Retail investors shying away had nothing to do with the IPO getting pulled. And even if this wasn't the case it's still not fraud: if retail investors have all the data (which they did) but still want to buy something, it's not deception.
Not "fraud" in technical sense; more like "generous marketing".
Running an ad of a bunch of thin, attractive people drinking Coke is not fraud. It's also not very accurate either.
