Ask HN: Is there less camaraderie among engineers?

Perhaps it's due to the current market situation and the bunch of layoffs that happened in the last years. I feel like software engineers (seniors and above, mainly) are less "friendly" overall. I mean:

- if you go and ask something related to a problem ("Hey, we found a bug in your service", "Hey, the performance of one endpoint your team owns is not that great", "Hey, your approach to X in your pull request is not the best perhaps", etc.) they will be very defensive and they will try you to handle it for them in the spirit of "breaking silos"

- everybody is busy shipping features to show in their next performance review. That means they have less time to help others (naturally, because helping others doesn't give as many points as shipping, so they need to make the best use of their time)

- whenever there's some help at last, they need to publish a medium-size post about it in a public Slack channel, pinging PMs and EMs and what not. Basically, no help can go unnoticed as that would mean missing "promotion" points

I feel like everyone is scare of losing their jobs or not getting a promotion. Everyone is on their own, basically. I think companies are taking advantage of this situation (I have talked with managers about this in previous companies, and they all agreed that that was the new status quo).
