I'm not against app store operators demanding a service fee... as long as they do a good job of blocking malware/spyware apps (Google doesn't, many GooglePlay-approved apps spy on you and send your data home), don't block innocent apps for sake of their own interest, let a consciously willing user bypass the store and, at last but not at least, don't demand a ridiculously high fee. A fee of 5% is ok, 10% is tolerable, 30% is absurd.
