Huh? What's wrong with centralized decision making and planning out everything for years? The rest I can agree with, but 1) in any company, you need centralized decision making or you won't get anything done; the point of a company is not to be a democracy, it's to be a machine that generates profit, and centralized decision making accomplishes that. And 2) what can possibly be wrong with planning things out far ahead? I worked at Intel for years and they did this, and it worked, for the most part. (Obviously, circumstances forced plans to be altered or even abandoned at times.) If you don't have a plan several years out of what you want to be doing, you're not going to accomplish anything big. How do you think the Moon missions could have worked if they didn't plan that out years in advance?
It sounds to me like you're comparing whatever little podunk 20-person company you used to work at with the big corporation you find yourself in now, and you're trying to assume that everything the little company did was somehow correct. It wasn't; the big company got to be a big company by doing something right.
Many of the other things you complain about just sound like typical bad management, and things you'll find in any organization that isn't perfect. Information withholding and saying one thing and meaning the opposite and ignoring inconvenient facts: aren't those common with the US government? I saw these in several small companies I've worked in (and big companies too). It's not unique to big companies. There's definitely more of it in poorly-run companies, which should be no surprise. There's no shortage of poorly-run companies out there, big and small.
As for the motivational posters, that's a fad (though admittedly it's been around a good 15-20 years now). I recommend getting your own motivational posters and hanging them in your cubicle (if you even have a cubicle; working at big companies was a lot nicer 10-20 years ago before this idiotic "open plan office" craze). You can get some excellent posters [here](https://www.despair.com/collections/demotivators).
