I don’t consider resorting to (any) ad trackers being an ethical way to earn revenue. First, because the site/app owner doesn’t really have much control over the relevancy or legitimacy of ads shown to users (ad network admins may be doing their best, but scams will still make their way through - hey there, Unity Ads). Second, no, I’m not letting you to fingerprint me across basically all websites I visit to enhance ad relevance, since most of it ends up being like intrusive thoughts anyway, with no real use for me. In the end, it’s just distracting, annoying garbage cluttering the view. I’m sorry I couldn’t explain my position better.

The internet was better when the only kind of ads out there was contextual, for money or just by friendship. “Hey, so you’re on my site reviewing various types of coffee? Check out my aunt’s coffee shop in Prague, they’re making excellent cappuccino! Click here to visit their site!”

Likewise, I would much rather prefer a service with limited functionality (e.g. ability to download only the latest version of an app in this case) in its free version to a service that throws a pile of shit at you, then asks if you want to clean yourself from it for a monthly (quarterly, yearly) fee.
