Your argument doesn't take into account the absolute market size and influence. No one is churning out propaganda on the other companies you mentioned because those markets are either much smaller or much harder to manipulate than Google's market.

Why would people try to cancel Luxottica? Eyewear touches a much smaller market and doesn't have nearly the same potential to manipulate people as Google does (at least not yet). People will always focus all of their attention on the largest threat.
