My big pet peeve is "required cookies". Dear website, this is my computer, I own it. I get to choose what data gets stored in it, and what my CPU cycles do.

A related anecdote. Back in college, when I first got serious about using #Linux I came to the realisation, that while windows task manager stopped you from ending any process it didn't want you to end, Linux's `sudo kill -9` would end anything you pointed it at, including the `init` process. This of course promptly would crash the computer, but it was a great feeling to have the machine do what I said, even if it was self evidently a bad idea.
