I think what you're saying is fair, tbh. Imagine you put in months or years into a project to make it a quality piece of work. It develops into something notable and you took all the risk. Then someone comes along to fix a spelling error with a pull request so their name effectively appears on the repo as a "contributor." And you just know right after its going on their resume as "contributed to [...]" or maybe if they're bold "software engineer working on [...]" which implies substantial investment. Then you're effectively sharing credit for YOUR work with someone who did nothing. That is rage inducing. ((Of course: it probably is just juniors trying their best in this horrible industry.))

On the other hand: lets be careful not to dismiss valid but inexperienced attempts to contribute. Having someone want to genuinely contribute to your software is incredibly generous. If someone seems like they're trying its better to give advice than act like a snob because its not good enough. Often pull requests only need small fixes to get in, anyway.
