There's no question that, in general, people expect businesses to provide a valuable service that does not harm society in the process. Of course, the consensus as to what things are valuable and what things cause harm changes over time (as is clearly the case for cigarettes). As well, when people sense a violation of their expectations, they should certainly take their outrage with them to the ballot box.

But when people sense that the ballot box isn't listening; that the government is both in bed, and emboldened, by the very thing that violates their sensibilities, they often step outside their part in the social contract and do things that speak louder than simply voting, like destroying property. If you are a US citizen like I am, you will know very well that this method of "discourse" is a foundational and often celebrated act in American history.

These people destroying a few cameras here and there aren't solving the problem of invasive and unaccountable government surveillance. But they are speaking their passion about it, not just to the company or the government but to their fellow citizens. And it looks like some people are starting to listen.
