"Only fairly recently did people seem to start using all these proprietary protocols that lock people into various things. Why they did that, I have no earthly idea...." The answer is inherent in the question. To lock people into various things (i.e., the hardware and/or software I provide for them, in return for teh monies). I mean, seriously! If they can just move their data anyplace they like using standard protocols, I have no leverage. I have to actually, you know, WORK for their patronage. I have to provide competitive services at competitive prices. That's hard!

"Excited Delirium" is the technical term for what a corrections officer friend of mine refers to informally as "naked sweaty guy." Sufferers from ED often experience a temperature spike (hence the sweating) and frequently strip off their clothes as a result (hence the naked part). It's usually the result of mental illness or drugs or both, and it can radically alter their responses to stimuli including pain. You can't reason with them, and they often fail to respond to commands, or to pain compliance holds, and can be extremely difficult to subdue because they ignore injuries that would normally be disabling--or even lethal--at least for a while.
