I'm hoping this kind of immature and abrasive behaviours will not propagate (notice the plural here). Yes, when you see a package being actively maintained by somebody else you should absolutely not touch it without talking to that person or team first. This is probably the single most important rule in Gentoo and I would like to thank Ben for reminding us of it. But nobody owns anything in Gentoo. As a developer you're not king of the hill but servant of the users. The only way to make yourself more relevant is by doing a better job, not by barking at the others to protect your territory. By the way folks, a better job also involves communication and behaviour which is what we all generally suck at.
