I wish there was more pushback against this insanity. I've also seen people want to erase the word "blindspot" from the dictionary... Even though I'm sure no blind person was ever offended by it, because that word typically is used to refer to the limits of people who aren't blind.

For what it's worth, in support of the original comment's claim, I just dug around the Pixelbook documentation all over the place and I can't find any mention of the motherboard. But it doesn't seem they renamed it to "mainboard" or "birthing person board." They just dropped it from the specification completely and don't tell you anything about what kind of motherboard you're getting.
