Well, it may be actually due to the fact that schools often lock down the Chromebooks so you simply cannot install another operating system on them, and if you do manage to it will be quite a headache and may even include fines (at least for my former high school). I couldn't even install real apps on my Chromebook (all I had was webapps and extensions), even though the feature was already technically out there (it was just locked down my school).

Also yes, as a Linux user, I really hated my Chromebook.
