With a looming iron-grip marketers and advertisers have over pretty much anything in their reach, why aren’t the masses collectively making harassment campaigns to them?
I think if we actively told every single marketer off in a prolonged effort, they’d get a hint as to how much of their commercialism we don’t need shoved down our throats.
Adnauseum covers the situation of how and why their solution at length in this research paper linked on their website if you’d like to get the meat and potatoes.
But to be brief, from my knowledge of how the software handles webpages (at least from my limited background as an Electrical Engineering student), the sandbox is only utilized to load enough resources to register the click to the advertising service by the website - you aren’t sent to the redirected site/content, and apart from the image of the ad being able to be seen from the vault in the extension, no external content is loaded. This is a safe way of handling things, especially since the sandbox is not granted access to the full privileges provided to you, the user.
