They have some personal issues, from not having slept well to more deep rooted stuff, and they take it out on the internet on whatever attracts their attention and can justify some "hate".

I doubt if perfectly normal people care if Ryan used "to my wife" or "to my spouse" etc.

If someone wrote "How I explained Monads to my husband" I could not care less normally -- but on a bad day, I could take offense for similarly BS stuff, like "how dare you write that shit about Apple", etc.
