As a fairly young programmer, I think it's not necessarily hero worship (though that does play a part). I think it's because a lot of young programmers define their identities in terms of what they do. This is especially prevalent in the free software community. If you're going to define yourself by what you work on, it doesn't seem very fulfilling to just keep an existing project running without having the freedom to make drastic changes that would improve the project.
It should noted though that the above points about Red Hat and "boring" (as much I hate calling people's work boring) don't sit right with me. I know quite a few people who work at Red Hat on very interesting technologies. At SUSE, I work on fairly interesting technologies as well. The key aspect that makes SUSE (or Red Hat) "boring" is that we have effectively solved the problem of release engineering and maintenance (though in recent years SUSE has been improving on it further through openSUSE Leap and the recent plans for SLE15). The funny thing is that if upstreams could do their own release engineering correctly, SUSE and Red Hat would have a weaker value proposition.
The "boring" comment isn't meant to denigrate people's work. Rather, it should be taken as a complement for a job being done well. In fact I've heard the "boring" comment from a couple RH employees myself. So, I think they understand what is being said, rather than taking it in a derogatory manner.
