That is victim blaming, just because you do not know that everybody out there is tracking you does not mean that you have decided to let them.
I agree that this is something people should be more aware of and school is a good place to start. However it is up to browser manufacturers to fix this, not users.
The comment says "it's as if" you are intentionally leaving traces everywhere. So, the effect is the same as doing it intentionally, not that users are to blame somehow.
