Ruby's got a lot of software that's been produced over the years, and one of the risks here is that people burn out on projects and move on. A slow accumulation of dangerous deadwood occurs over time and unless people work to clear the brush it can be catastrophic when problems strike.

Consider: ImageMagick and OpenSSL.

Newer platforms haven't had this problem because they've already broken all their old software (Rust) or because they're still changing rapidly enough that new software is still emerging (Swift).

It's not the community's fault. It's that it gets harder and harder to keep things clean the longer your language has been around.
