Can dang do something about the corporate spam that keeps popping up on HN? I don't think meta, or Apple, or the rest of these companies need help advertising products.
1. Flag content you feel isn't appropriate for HN.
2. Email mods at hn@ycombinator.com requesting that specific sites be deprecated and/or penalised.
As for the latter, I'm aware that general news and ideological sites are deprecated. I'm not aware that any mainstream corporate sites which have not engaged in vote-juicing practices are penalised.
There are those who share your weariness of promotional material from ... a certain commercial toothed segment, let's say.
