Again, a lot of these companies have also been around so if my app has a ton of bloat from years of work, we're bringing in frameworks from other companies who have been around for years as well and probably have a similar amount of crap in their code. Plus they probably want to track everything we're doing so they're bringing in their own third party libraries. It's kind of ridiculous but that's where we're at.
Bigger companies won't have as many third party libraries as they can afford to do it in house but they're still bringing in similar sized libraries to do the same things.
