Forcing someone to use a different form of media to get acceptable support for your product is pretty bullshit. If I can sign up for, pay for, and use your product for years without a telephone, I shouldn't suddenly be forced to use a phone to get support.
Even if that might be the best solution at this point, it's still garbage and something to justifiably complain about, especially considering it's mildly infuriating we're talking about.
Linux kernel doesn't include a spell checking dictionary soooooo Linux doesn't worry about whether things are words. Your particular spellchecker doesn't seem to think linux is a word but "aspells dict on my machine doesn't consider linux a word" sounds a lot dumber (because it is pretty dumb)
