I've identified my biggest pain point when these companies try to pull shit like this: it is the audacity for them to pretend like they have some authority to decide anything for me (as a user), or even nudge me in any directions, be it in content, ways to use their service, etc. ...
Dear Reddit, (and the likes),
You are a service company. You provide me a service. You are not an authority, or a thought leader, or anyone who's opinion I for some reason automatically respect or am interested in. You simply make it easier for me and users like me, to aggregate information and to share data, in a format that we like. You did not create that format out of thin air and you do not own it. It is we, the users that told you that this is the format we wanted to use, by going to your website and not competitors. You A/B-tested it from us. This does not give you any authority or right to pretend like you know what is better for us. You are simply a utility provider. Start acting like one. I do not care about your opinion about anything, let alone how I should use your site, what I should read, what I should buy or not. I just want a service, the aggregation of information. The utility of it. I don't care about how you make money (none of the users really do, let's be honest). If you stop giving the utility, I will go somewhere else. If you can try to provide this utility and also making money in the process - good for you. If you ask me to pay for your service, a fair (!) price, I will gladly do, like I do for any utility like electricity, clean streets etc.
The more shenanigans like this you pull, the faster the decentralized versions of those utilities (a useful forum for quick information, in your case) will come up and eat up into your revenue.
