Seems the HN software killed the post. Vouched as this seems like a reasonable query. Sorry to hear your troubles ... but my 2 cents is that if upstairs have to call you in to answer the questions your manager could not ... and you straightened out the mess, upstairs would know you and the team are the people who do the hard work. The same for higher ups asking for your help to train your own manager. If you're earning more money, bonuses etc for your additional roles, I guess that's fair enough, or the job just pays ridiculously well, doing extra stuff shouldn't be a problem ... but I can sort of guess from your outline, it's not that way at all. I have little idea what it's like at any of these big companies {and I'm out of doing anything remotely computer wise for a couple decades (memory leakage is a bummer among other things,)} - but I'm familiar with how a few really big companies (entirely not computer or web related business) like to work when they can get away with things down my way ... they see managers as a simple tool to get the most out of people, they don't have to have much talent past doing whatever it takes, little lies/ very unlikely to materialise promises that need to be told, and proving a buffer for when someone has to held to account.
