the problem is, corporations like Google or Apple, depending on which mobile phone you use, already know everything about you. they know your age, your preferred gender identity, and where you live. that alone is enough for them to make very good guesses at the kinds of things you would be interested in. but the information they have on you goes much further than that.

trying to poison the well just through a single browser extension doesn't do anything to change the data they have on you. especially since you can't poison all the data they're collecting on you. that extension might not even work on mobile, and even if it does, most of the information they collect doesn't come through your browsing habits, it comes from the things you do in the apps you use.
