Good point, this is probably my experience at a FANG talking, I was like that early in my career, based on my experience at university where it was mutually beneficial to support others. All things equal I didn't get promoted any faster than the others so I adapted my behaviour. What you experienced is what good management should actually look for, in my case that showed that the team and company goals were strongly misaligned with my personal goals.
Outside of big corporate I've seen more value in helping others, though it still makes sense to evaluate if someone is repeatedly taking up time without returning the favour when the situation arises.
To be clear, I don't think it's good to ignore people, but I think it's important to show boundaries, if someone wants something, they should be considerate and have fair expectations. A well written request considering my situation would very likely get a quick reply.
