Maybe - but the marketing that won't affect you isn't what you need to worry about. It's the parts that do still work on you need to be careful of - and if you assume nothing will ever work on you, you won't even notice when something does take. Whether that's buying a trinket that doesn't actually make you happy, or joining a group that turns out to be a cult.

Always better to assume you can be manipulated, and check in with yourself periodically.
