The question then becomes; is it bad if Mozilla were gone? What is the added value of Mozilla and their products right now?
Without Mozilla the Microsoft/Google/Apple triumvirate will control all browser standards. I think Mozilla brings a different perspective that would be missed. It would be nice if Firefox OS gained enough traction to make a similar difference in mobile but the chance of that happening seems slim.
But I've certainly had cases where I needed to copy and paste a few lines of code maybe even 100 times and then tweak each instance to put in the data values or validations I want.
This leads to bugs where a tweak gets missed in one of the copies (copy, paste, do tweak 1, interruption!, forget tweak 2). It also causes maintenance problems when the person coding a bug fix doesn't know there are a bunch of other places that need to be fixed.
Happiness is twin floppies.
