Kickstarter does not market itself that way. Kickstarter is misleading about what it does and how it works. That people say things like "pre-ordering" indicates it.
There are significant differences between a pre-order and backing. There are accounting differences for Kickstarter and there are less guarantees for backers than for pre-orders. You aren't entitled to any of your money back, support, or timeliness. Pebble Time showed up at Best Buys before backers got their watches. I bought my Pebble Time from the pebble website and people were still complaining about having backed the kickstarter.
With a kickstarter you're shooting your money into the void and hope something comes back to you. With a pre-order you're legally entitled to a product or your money back and receive benefits from the various federal and state laws that govern how businesses do commerce.
