"I guess the thing not clear to the average user is that the ad and the app are one."
I just don't happen to agree with the entire model. YMMV.
"As a developer not only do I not like messing with the ad libraries but I must redesign my application screens to make room for the ads to play. I think the ads "crowd" my apps. And the companies that act as the middle man for the advertisements are generally slow to pay out so it takes a lot longer to get reimbursed and as mentioned in the article reimbursement is at a much lower rate than the 70% I get automatically when someone purchases one of my apps."
Or maybe your mileage doesn't vary much at all.
"It's difficult for me to feel overly sympathetic for a user who continues to use a trial version of my software yet won't part with 99 cents or $1.99 or whatever I think is a reasonable amount for something I put my time and effort into creating and releasing."
I'm not terribly sympathetic on that point, either, although I find it to be a separate issue from bad and invasive advertising models.
Whatever, this behavior is ingrained. People are used to living with ads in a lot of software. People are also used to getting functional, good-quality, ad-free software for nothing. Roaming device application consumption has about twenty years of desktop-style of application consumption inertia to overcome. Give it a bit.
"Sorry to get on my soap box."
Sorry, I hadn't noticed that you were pontificating.
