Someone else pointed out it’s not that difficult to boot Linux on your Chromebook off a thumb drive. A quick search shows it might be slightly complicated but seems pretty doable depending on your model.
Listen I hate Google, but this still seems like a dumb take. There are better things to criticize them for: illegal monopolization of search through anticompetitive practices, making their search product worse on purpose, having no respect for people’s privacy, literally removing their slogan to not be evil, etc).
