The problem is that when we were young, not posting under you own name and cleaning cookies was virtually enough to keep you anonymized on the Internet. A teen wanting to discretely inform themselves on, let's say, sexual orientation, need to be careful about e.g. their Windows account and/or use a public device, mind their Chrome/Edge/... account, use another search engine than Google, use porn mode, be sure that the page they visit is not using Twitter/Google/Facebook/... trackers, clear cookies, clear profile, be careful with device fingerprinting, browser fingerprinting, etc. At some point, this is a losing battle.
