Both as a developer for nearly all platforms, and as a consumer, I despise software monetization through ads. Sure, I understand that not all apps have a clear method of monetization, and so many developers rely on ad revenue to offset their development time/costs, but I personally won't touch their adware, period, meaning they lost the opportunity to monetize me at all. Adware wasn't acceptable to me in the 2000s with ad supported Windows software, and it's never been acceptable to me on iOS, Android, or Metro, or any other platform since then. It seems to me that ad supported software was largely rejected by consumers up until the proliferation of smart phones, but I still reject them and refuse to support a business model that under the hood is really after collecting consumer data. From my prospective, adware is spyware, albeit less innocuous, but still privacy invading, unwanted, and annoying.
