Filtering By License Should Be Possible in App Markets

tonymercmobily writes "With the latest news from Microsoft, which will allow open source apps in their store, we will see more and more an abundance of per-pay applications mixed with license-free ones. What if you can't tell between free and non-free anymore? Even now, a quick search on the Android market is just not telling enough. But what do you do then when Ubuntu has the same problem?" For Android there's always the F-Droid market that exclusively lists Free Software (it's small, but I've found it pretty useful).
