Distros shouldn't waste time and effort on supporting and packaging language-specific, high-churn code packages except in very limited circumstances. Let the language specific-tools do those. Upstream is best, local fragmentation is wasteful.
False dichotomy fallacy. Linux distributions need to engineer for side-by-side installation of multiple versions and not get tied up to those common locations. nix is just one example as an interesting idea, while Homebrew and stow are better ideas.
More "innovations" which "justify" their own existence with novelty, but eliminate useful properties, backward compatibility, interoperability and standards with blissful ignorance. Standardization is a Good Thing(TM)... many formats creates a confusing dependency hell across multiple systems. Deb/apt works well. This will be deprecated in 6 months after a major security incident. Canonical is mismanaged and capricious, and this is just another in a long line of examples.
Those three (3) Hillary speeches must be absolute mana from heaven because her standard contract includes a client-paid stenographer, in addition to the $200k/ea.
Only fools would give these access-buying, crooks a dime... unless they wish to continue subverting freedom with this plutopsephocracy.
Third-world country edge-cases. Murder is still murder. The preponderance of donations in first-world countries saves lives, but is so rarely done despite the pressing demand. When you or family member needs a life-saving transplant, which system would you want?
The one where the organ was freely and explicitly offered, not harvested from a person who might have mistakenly believed their body would still be theirs in death.
