Bush-era antiwar groups, Occupy Wall Street, leftist political groups, security researchers, environmental activists, whistleblowers, lawyers representing "sensitive" clients, and MLK himself... all have faced some kind of illegal surveillance or intimidation tactics. (There are many known targets that I didn't list here, and likely many that we don't hear about, simply because the oppressed often lack access to media channels.)
I would much rather be manipulated into buying more Coke than targeted for harassment, intimidation, no-fly lists, and smear campaigns because of my political beliefs. Not that marketers are angels, but they don't hold a candle to the type of abuse that the government can dish out when someone is "marked" as inconvenient.
