Censorship is the suppression of content in order to exercise political power and control. Refusing to show something because it means you'll make less profit is not censorship; refusing to show it because you have an ideological belief that the viewer shouldn't see it is. Consequently I guess it'd be next to impossible to demonstrate a business is actually censoring content rather than removing it for the benefit of the business.

The end result is the same regardless of what you call it though. That's what needs to be addressed.
