No, I wrote "binary". Also, Featherwiki is not an app. Most apps I download from f-droid are quite small and the bigger ones contain images, sounds and even animations. 2 MB are a lot for just CPU instructions assuming we are talking about compiled languages. Of course some languages can create very large binaries anyways - but that's due to their inefficiency. In fact, ls -Ssrh /usr/bin shows that the vast majority of binaries are small than 200KB, ignoring symlinks, and the outliers are databases, compiler and few other very large applications.
