I think they were referencing mountain bikes. They are nearly all 1x now.

  .. and i still don't understand how we're all just supposed to ignore the monster chain crossing that this setup implies.

    It doesn't seem to be much of a problem on my 1x mountain bike.

    It's less crossing than 2x at the extremes

    I run a 1x10, and there is no problem with chain crossing. The 10/11/12 speed cassettes are basically not any wider than the regular 9 speed ones, so there is no more chain crossing than what you get for the middle ring on a 3x9. The optimization is all in narrower chains and sprockets. That being said, I do run an upper chain guide to reduce probability of the chain falling off the chainring when the rear derailleur gets clogged with mud etc.
