Earlier quoted context omitted.
If someone gets angry about a badge in an app, it seems like they have a deeper issue to deal with.
If badges motivated learners to do things that benefited them, but now (they feel) badges motivate behavior that benefits the app maker more instead … that would be a clear example of enshittification. Rule 34 needs a twin: Anything can be useful. Therefore, anything can be enshittified. And will be. Period dot period. QED. I have spoken.
But you don't know that the aggregate user base feels that way. In fact, it might actually be much better for learners, like the top comment says: https://news.ycombinator.com/item?id=36611749
The person I replied to talked about 1 person getting angry about the change, but that doesn't mean it is bad for everyone and is not evidence of enshittification based on data.
