I can only assume you've never worked at a company even close to the scale of Amazon. There's no such things as "fixing it" with a lot of these internal tools. They'll often have entire teams dedicated just to developing these tools. More often than not you won't even have access to the source code and even if you did it would probably be incredibly difficult to make any meaningful changes.

You say it would literally be faster to stop feature work and fix the broken thing which is a laughably naive view on how these companies operate. That's just not an option unless you do it all on your own time in which case you will still be incredibly limited on what you can change and even if you make a significant fix there will be no extra reward for doing so. The incentives are all wrong.
