Personal anecdote: I've recommended and set up quite a few elderly people with Chromebooks with the same thoughts. Multiple times, I've checked up on their installs and found their accounts riddled with malicious browser extensions and search engine hijacks. They claim that they were aware of not clicking on stuff asking to install browser extensions, but they got tricked (multiple times) anyway. I suspect that the search engine hijacks helped the process. After having this happen many times, I'm now of the stance that while ChromeOS itself is far more secure than Windows, it's very far from a turnkey silver bullet. You really need a multi-prong strategy (ChromeOS/iOS, uBlock Origin/reputable content blockers, user education and vigilance, etc)
