The test for a good HN post isn't whether something is corporate, it's whether it gratifies intellectual curiosity. I of course agree with you that most corporate PR and advertising doesn't remotely clear that bar, but occasionally it does and such posts are fine on HN.

This is one of those cases where it's really helpful to know specifically what we're optimizing for and what we don't need to worry about: https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sor....

Well, I don’t think you can really stop people from talking about new technology on a forum for hackers…

You can:

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.

I dislike Facebook as much as the next guy, probably more, but this stuff is news for hackers. And it's not even particularly beneficial for them to be featured on HN, we're a rather critical audience.

A tech giant is using luxury branding to encourage people to put networked cameras on their faces.

I think that's worth my attention even if I'm not the intended customer.

Because YCombinator is not "corporate"...? Dude.
