Long, baseless angry rant
your entire argument is based entirely on your (very clearly strongly biased) opinion, no fact whatsoever.
Apple has sold MILLIONS of copies of lion on the app store (meaning those copies didn't come with new macs). It was adopted faster than any other operating system.
All of the limitations of the iOS system you pointed out are very real. They aren't, however, relevant. There is no indication that those "oversights" are going to be brought to OSX. They are only bringing the features that make sense for the desktop.
The file system in lion is slightly restricted, yes, but hardly at all. Apple has hidden and locked system essential files. We're talking about the average user here, so how is that change going to affect them AT ALL? It will only keep them from accidentally ruining their system.
Certain locations are hidden by default in the finder sidebar. They can still be found through search, and can be turned back on in the preferences. It takes literally 10 seconds. You don't seem like the type who uses the default setting on their computers, so that shouldn't be a problem for you. Aside from that, nothing is "gimped" or a disaster about the file system in lion.
A full filesystem is included in windows 8 (just like in lion, by the way) but it is "hidden" from within metro apps, in favor of more intuitive, software driven solutions.
And you've also completely ignored my statement about how share sheets function. You claimed that if the developer doesn't think of a certain app to be shared to, you are out of luck, this is totally wrong. Share sheets work by telling the system (when you press them) "I'm trying to send this .pdf, .jpeg, etc". The system spits back a list of apps that tell it "hey, I can use that file", and the user chooses which one they want. The app needs to have only information about what file types it can read built in, no information about where it can share to, the system handles that.
Your claim that users don't want to share between apps is totally absurd too. Drag and drop is one of the most popular features in OSX, and it's for sharing between apps. Users want that, they love that, and share sheets make it a lot easier. Oh, by the way, drag and drop isn't going away either.
It's the future of computing, you don't have to like it, but you can't deny that for the average person it IS better...microsofts engineers recognized that. I don't know why you cant
