I'm not sure what to do about this, but there are increasing signs that it's a problem. HN is what it is because it has a specific, opinionated, highly intentional design. It's fine to disagree with that design—plenty of users do. Probably every user does in one way or another. What's not fine is for third party clients to break this design in a way that alters the community itself.
There's also the fact that some apps are now charging money, which feels to me like a violation of HN's spirit, which has always been to be completely free. I like to say that the currency of HN is curiosity, not money, and we'd like to keep it that way.
We may have to produce some sort of standards for HN apps, which is a drag because that sort of bureaucrat is the last thing that any of us is interested in being.
