On the developer side I see the opposite: End users that are complaining can now deal with problem themselves without having to pester (or even find) the developer.
Anything that amounts to less pestering of developers is (probably) a good thing
I'm unsure of how the burden of proof would work if the developer is not involved. The end user may have a hard time even guessing whether a piece of GPL software is embedded in the defendant's software.
