Japan banks may hijack Olympus (Reuters)

I don't understand the reasoning in this line of complaint:

J-banks are the biggest shareholders and the biggest creditors of Olympus, so of course they should have the biggest say in the future course of Olympus. Of course the interest of minority shareholders should be protected also, but nothing so far suggest otherwise.

I think the true reason for some of the whining from foreign shareholders is that Olympus is shunning their preferred bidder: private equity -- TPG made an offer a while ago and it went nowhere. PE firms have been frustrated in Japan for a long time, and it's not likely to change anytime soon since cash-rich Japan doesn't need their money.
