Consider the way Kickstarter projects describe their "backers". On the "Why Kickstarter?" page they say backers are "helping to create something new". Yet, one could easily consider Kickstarter simply a website for pre-orders, no different from buying in any other method.
The line between a buyer and a backer/builder isn't so clear.
It is pretty clear, if you are funding someone'e kickstart project then you did help them build it but if you pay for a product which was built using the creator's(or some other investor's) money then you did not build it.
It's even more fuzzy when you consider beta customers for a software company. Heck, how about when I contribute information to Google Maps? Or give feedback and make feature requests for my accounting software?
Which is "no". Buying and building are two different things. So I guess you were right about what I intended.
