The "license hoop jumping overhead" is a legal requirement. If it ever comes out that your software contains code copied from some random web site, you're asking for a copyright infringement lawsuit. If you stick GPLed code in your code base, then your entire codebase is GPL and you're required to give away the source code on request. Even if something is MIT or BSD or similar license, you probably need to give the author credit in your software (this is why so many games have an "Open Source Licenses" option where you can read the licenses of various open source libraries they stuck in the game). If you forget to credit the author of the MIT licensed library you used, that's also a potential lawsuit.

In short, don't play loose with software licenses. The legal system has about as much interest in debating whether a company has to follow intellectual property laws as the tax collection agency does in debating whether you have to follow tax laws.
