Well you sort of answered it - I don't have a problem with people crying in a stressful situation - just don't like the idea that we should coddle insecure people because they have confidence issues. Also 19 is a teenager - I prefaced my comment with it being understandable for younger people building their self image/novices.

Snarky comments forget that there are people behind those projects - but there's this implicit assumption that any contribution is a good thing and it should be encouraged. Poor contributions that are not called out just are traps and time wasters for other people - as someone who had to dumpster dive on NPM in the past - no contribution is better than a poor one because poor ones waste time and create noise. It might make the author feel bad but it's better for the community.
