There are always two ways to look at things. In the case of Wikipedia and similar high-traffic websites, it probably takes a bit of the load off. It's probably a considerable saving in terms of serving requests if a user searches for an actor they think they recognise from a movie and see a snippet from Google served from Google's cache rather than a full pageview from Wikipedia. In the case of physical stores and offices, I would imagine that a check for opening hours or telephone number shouldn't be counted as a pageview -> conversion anyway — they already chose you i.e. converted. Maybe they're a returning customer or somebody who liked the email marketing you sent them. Is Google Maps stealing traffic from you by showing your business on the map? Maybe, but they're also doing you a favour. Neither Google nor Google Maps are likely to go anywhere anytime soon, and a considerable number of people are only going to check Google Maps and won't bother checking your site for the same information w.r.t. your business's location. Beneficial in terms of reviews as well — displaying the aggregated score in a rich snippet is arguably preferable to letting the user click through where they can be persuaded against the 4 star average by an impassioned negative review. Google obviously wants to be the one and only gateway to the web, and they want to keep you on Google pages as much as possible to show as many ads as possible, but unless you're selling ads, counting pageviews/traffic is pointless unless it's new business, and people new to you are unlikely to make a snap judgement based on a rich snippet. If anything, it's more likely to convince the new user to click through to your site. [IMHO]
