IMO it may (not sure) suppress a few contributions but I don't think it'll have a meaningful impact at all. I personally don't contribute to dev.to (yet, lacking time and energy) but I wouldn't be bothered by this if I was. I think it's very good to enforce some rules for your code (had a discussion about that with a co-worker this very morning) and linters are a very good way to do so.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
