I use Linux on my home computer, and I'm sure the penguin is over-represented in Android users compared to people with iPhones or Pocket PCs. Similarly, given that the Android OS is essential Linux, I reckon that a lot of the devs for Android have cut their teeth on Linux. So, my question is what's happened to the Open Source Ethos? I don't have any Ad-supported-$2.99-to-upgrade programs on my Desktop. Open Source programmers are happy to work on their projects for the love of the job, love of the penguin and the good of all. On Android? Nah, have a banner ad, suckers! I'd been keen to hear what people think. Is it just an economy of scale? Android is taking off so can't be maintained for free, or have people finally given up on free-as-in-freedom or free-as-in-beer and moved to free-as-in-pay-for-it-you-cheapskate!
