I can see 10 potential objections to this:
1. The fear that ads served by Apple will provide a worse user experience than the ads already served by other services (seems extremely unlikely to me; ads already include everything from video to interactivity, and ideally you dont get any of that unless you choose to tap--but with or without Apple, thats always been up to the developer; do we really think Apples going to force unto us some whole new type of ad thats more obnoxious than the status quo?)
2. The fear that ads served by Apple will be a real pain for developers to deploy, compared to other services (again extremely unlikely)
3. The fear that these ads wont take the place other services, theyll be in addition, so we see more ads than ever before: Apple-served ads alongside other services ads (again extremely unlikely: if a developer wants 2 ads theyll show 2 adsone more ad services wont help them do that)
4. The fear that Apple will force developers to stop using other ad services theyve already contracted with and designed their apps to use (again extremely unlikely)
5. The fear that Apple will include ads with the built-in apps, so you pay a fair price for hardware and then are also forced to watch ads (absurd)
6. The belief that more options for developers is a bad thing (but the option to show ads has always existed, with or without Quattro or Apple, and the option to sell paid apps is not going awayso buyers can keep voting with their wallets, and some people will always prefer free while others prefer paid)
7. The belief that Apple will allow ads in paid appslike cable TV (maybe, maybe notit could make sense in some cases where an app requires expensive servers foreverbut developers wont have to USE that option and few will: because that has ALWAYS been allowed, and users have always been free to take it or leave itor give bad reviews)
8. The belief that free content should not exist at all, not even as an option for those who want it (but I for one do!)
9. The belief that good, quality free content doesnt cost anything to create, and therefore should never have ads (but in fact it does cost something)
10. The fear that Apple might succeed in this business, and harm other ad companies that deserve more of that money themselves (I cant see myself caring)
