- Maybe a couple of people will think, "Meh, another ad-based monetization business plan. I'll live with it."
- Many people will see this and think, "Ads? Forget this, I'm using gchat/facebook/facetime/other free video service without ads."
This, to me, is what is wrong with all basing your revenue on advertising. Skype's mention that "this will make Skype more engaging and useful" is laughable. Basing a business plan on advertising is a decision to provide a cheaper/free service at the cost of deliberately worsening the UI and, ultimately, the user's experience with your product. That's a serious trade-off indeed.
