How profitable is Cydia, the jailbreak app store, and what happened to the Mac version of Cydia? Jay Freeman (Saurik), the founder of Cydia, recently provided some answers. The explanations were prompted by disgruntled users venting over Cydia's lack of updates and the whereabouts of a Mac version, and ended up as a mini-interview of sorts. In response to claims that Saurik keeps 30% of every app sold in Cydia, like Apple does with the App Store, Saurik provided details on where a large portion of that 30% actually goes. From the ModMyi thread:
100% - 70% (developer) - 7.5% (PayPal) - 7.5% (EU VAT) is nowhere near 30%. Cydia also bears a greater cost than I thought it would for outgoing payments (as almost every developer makes no money, so the PayPal fees end up being really expensive every two weeks to send "almost no money" to thousands of people), and if you subtract bandwidth and servers and the two employees SaurikIT does have, you are left with quite little; what is left is spent back on the community, including bandwidth for non-Cydia things such as jailbreaks/TinyUmbrella, sponsorships of open conferences, etc. That TSS/SHSH server I run that people love so much alone costs many thousands of dollars a month.
The difference between revenue and profit (revenue minus expenses) seems often to get confused, not only with regards to Saurik but Apple as well. Just like Apple's App Store and Android's Google Play, Cydia costs money to run, and a huge amount, if not all of the revenue generated from them go into bandwidth, hosting, transaction costs, and everything else that goes along with running such a large online store.
Saurik also explained -- again -- why the Mac version of Cydia was never released, and what happened with efforts to create a Mac substrate.
As I have stated on numerous other occasions: I got almost universally negative feedback from it when I announced it, including entire articles online calling me stupid for even having suggested it. I seriously left a conference early feeling like I had been half-laughed off of the stage for even suggesting the idea (yes: that's definitely an overstatement of reality, but I kind of felt that way at the time). It wasn't until half a year later (when Lion was released) that any reasonable number of people decided to say "maybe saurik isn't so stupid after all".
Saurik also talked about the Rock acquisition, Winterboard vs Dreamboard, and a few other interesting topics.
