Companies should invest in the open source they depend on, otherwise they will need to re-implement it from scratch or maintain an in-house fork with higher costs. You may be spending those sprints implementing a workaround that you will then have to touch again when the problem is eventually fixed upstream, or you will run a private fork that you're stuck with forever and will have a hard time maintaining.
As for the complexity, from my experience it's a mix. There are indeed many complex issues, but often times the fixes are relatively easy and take little time to fix.
For the hard ones it's often enough if you can contribute to the conversation to better understand the problem, providing valuable information on how to reproduce, so that someone familiar with the code base can solve it easier.
