Hi,
we might introduce an option to purchase a subscription to remove ads (this is hard to tell at the moment), but the ads themselves in the free version are not going anywhere (at least not anytime soon). One doesn't have to be a genius to see that we switched from direct monetization (subscriptions) to indirect monetization (ads). We need to let that run for some time then evaluate the results to see if it was the right move or not. After that we'll probably decide if we remove the ads, introduce a subscription to remove the ads or leave it as it is now.
I don't know about the pattern, but I have a good feeling about the fingerprint.
