Cyberduck, an FTP client, takes a similar (though easier) approach. You can buy it on the Mac App Store for $23.99 [0], get precompiled binaries for free on their website [1], or grab the source yourself [2].

Do you have any data / references to support this?

Not sure why he/she deleted their post, but for an excellent in-depth analysis of App Store pricing I thoroughly recommend Michael Jurewitz' 5 part blog post "Understanding App Store Pricing"

Theres a bit of Economics 101, and some very well explained real world data on app pricing. Essentially Michael's advice boils down to: try doubling your price. If you lose less than half your sales, you're now making more money than you were before.

I wish I could pay for Blink on Windows, because it's my main SIP client. Windows definitely doesn't get the attention that Mac OS does, but the client is the best one I've found. (I really grew to hate Bria/X-Lite.)

I never thought about it like that. I bought Textual because I wanted to support the developers.

The benefit of it being open-source was that I could try it, use it, and hack it, before deciding they'd done a damn good job.
