Reverse Thanks on Backerkit

Sometimes I back Kickstarters so I can add cheap toy soldiers to the ever-growing pile of plastic and metal shit that substitutes for happiness or fulfilment in my life. Sometimes once you've forked your money over, you have to allocate that money to the specific products you want from amongst everything the Kickstarter will produce. This is done using a site called Backerkit. Once you've sorted that out, which in my case typically ends up giving them more money because they've taken shipping out of what I wanted, this message comes up:

"Now it's time to thank your project creator!" What? Why? Is it just me, or does this make no sense? Why would I be the one thanking the project creator? I'm the one giving them the money that contributes to their project. They should be thanking me. I don't understand the logic behind this. Is the implication that I want this product so badly that I need to express gratitude to the business creating it simply for making it available for me to invest in? 'Cause that's not how investment works. I invest in a project and expect a return. I don't see how gratitude factors in anyway. It's a simple business transaction.

If I was more inclined to get worked up about things than I actually am, I might be tempted to say that this reeks of capitalism out of control, in which we have to toadyingly bootlick the companies which produce consumer goods for which we pay them our own money simply because they're giving us an opportunity to spend our money on things we want.

It doesn't make any SENSE!
