Web2 advertising has gotten absolutely obnoxious. Every 4th post I scroll by on Facebook is an ad. YouTube videos are interrupted by ads all the time, but many content creators I like are under constant threat of strikes and demonetization not because they are doing vile things, but because corporate Karens run the show now.
If you have ads on HIVE frontends, you have a delicate balancing act of appealing to HIVE bloggers, not driving then to other ad-free frontends to escape the deluge, and satisfying the goals of the advertisers. It's a big risk for all involved, really. And then there's the legal problems which may arise as well.
I'm not saying it's entirely a bad idea, but anyone who thinks there's an easy answer is nuts. And when you start talking about tracking clicks and read time, you also risk driving away people who value relative anonymity. We don't tend to want corporate eyes on us if we can avoid it.
This would be an opt-in kind of thing, if u don't want extra rewards then you never see any ads. It's on the front-ends anyway. You may still get some extra rewards depending on your HP holdings if the front-ends decide to share some of that towards holders, but yeah. If you don't want to, nothing changes for you except for people talking about the ads in your feed I guess.
If other people see ads in my feed when I have opted out, that could be a problem.
