IMHO I think they are different. So much of what makes the web and surveillance creepy is the ability to correlate across data sources. CCTV isn't creepy for one store owner to have - it's bad when the government has it everywhere.

It's not bad for people to analyze how users interact with their site. It's bad when one entity (or a handful) can track you across the Internet.

So in other words, I don't mind Piwik and have considered sending in a patch to uBlock and others with a switch to disabled "locally hosted analytics" or something similar. Like the drive to push "ethical advertising", I think it's reasonable to permit some benign tracking as a way to coerce more sites into decentralizing user analytics.
