this is really bad comparison
a subway platform ad doesn't dictate the way consumers use the subway.
a restaurant does not monitor the effectiveness of the ads in their menus, analyse their industry and rip off their product with an in-house brand (amazon basics)
amazon is not a marketplace, it is a surveillance platform built to allow amazon to take ownership of more and more markets
to say this is just a problem with ads is defeatist instead getting real tangible change
