I understand the sentiment, but I think the forgotten part on OEM installs is, current OEM offerings are on more premium models. I would be curious to see what would happen if Dell or Hp made like a 250-400 dollar laptop and put it on shelves in Best Buy and Walmart with Ubuntu, Pop or Mint installed. I don't know if it would work, but interesting to try. Like I said, most OEM install tries have been on premium hardware, or in the case of the PineBook, for the person who wants to tinker.

EDIT: Especially since winning on the desktop would be mass adoption. Most home computers are not Dell XPs Or Lenovo thinkpads. And marketing cheap laptops geared to students works in the case of ChromeOS
