The central promise of Open Source is not that you can get workarounds for bugs — it's that you are free to fix any bug yourself (or pay someone else to). Lots of non-free projects have great support too, but when you fall through those cracks there's nothing you can do about it. Open Source gives you a much better promise instead.
I agree. The appeal is that your options for workarounds are orders of magnitude larger than with non open sourced software. You have a multitude of options...
- Workarounds are still important and easier since the software is more transparent
- The communities are larger so paying someone else is easier
- Forks exist for a reason
- You could fix it yourself
