If you can't hide your activity just pollute their data to the point it becomes unuseable. Give them data that makes them lose money. Search random stuff you are not interested in and see them desperately throw money into the toilet. Search plane tickets to Congo, saxophones, windsurf equipment, paintings of toucans... the most random shit you can think of. Then you will start seeing ads for that, which is seeing the ad tech imploding in front of your eyes. The more you do it and the more other people do it, the less profitable ad tech becomes. Also search for stuff outside your demographics, like stuff for older people, so they get your profile wrong.
