Well, they surely aren't committing seppuku. No such thing as a corporate honor or shame, only business interests. At least, not with any large corporations.

And this status quo needs to change. Too much power and information disparity at the moment, the markets are essentially broken.

IMO, the easiest and most healthy way to get from here to there is by splitting those companies. There are plenty of ways they can be reborn, many even without hurting anybody.
