I am a "dependency skeptic." A lot of folks think I'm against them, but nothing could be further from the truth. Most of my software is composed of dependent modules.
I don't oppose the whole concept of using libraries. I just look closely at each library I'm about to include in my project to understand what exactly it's doing, what it's abstracting away, what are the tradeoffs I'm making, and whether its scope is too broad for whatever I'm trying to achieve. It's sincerely perplexing to me that not everyone does this.
The other biggie is legal and fiduciary exposure. That's usually neglected by tecchies.
You can't ask a lawyer, because they will always say "no," but I have seen some really bad things happen, because people didn't take this stuff seriously.
I never take this stuff seriously, but then I never really worked, or ever had the desire to work, on anything this proprietary, or in a company this bureaucratic. When my first employer was acquired by a giant corporation and I started seeing it transform into this monstrosity, I quit.
