"This is why Linux doesn't have spyware, doesn't come with browser toolbars, doesn't bundle limited trials, doesn't nag you to purchase and doesn't pummel you with advertising."

The shopping lens was openly added as a marketed feature, and could be turned off with one action. You could, I suppose, class it as spyware, but it wasn't surreptitiously sideloaded - it was touted as a default feature. It didn't alter the browser, wasn't limited run, didn't nag you, and while I didn't use it much, it could hardly be called 'pummelling with advertising'.

It was an openly-acknowledged experiment that failed, and was removed.
