I'd say that from the article SoftBank are operating in grey area of accounting regulation.
Combine that with the fact that those auditing/consulting firms are being paid by SoftBank and you can see a strong incentive for them to side with SoftBank's valuation strategy.
I'm sure the risk management people in the Big-4 are looking at this but I'd also guess there's quite a lot of pressure to let it ride, as I'm sure work from SoftBank + it's group companies is worth a lot of money.
It's been the case in many previous collapses, that the auditors signed off on the companies, sometimes quite close to the date they collapsed, and that wasn't even where there is a lot of ambiguity as there is here.
All this isn't to say that the valuations are necessarily otf, but that I can see the incentives that might lead to companies accepting them.
