Now, if Google or whoever really feels like fixing fast is so important, then they could very well contribute by submitting a patch along with their issue report.
Then everybody wins.
I don't want to discourage anyone from submitting patches, but that does not necessarily remove all (or even the bulk of) the work from the maintainers. As someone who has received numerous patches to multimedia libraries from security researchers, they still need review, they often have to be rewritten, and most importantly, the issue must be understood by someone with the appropriate domain knowledge and context to know if the patch merely papers over the symptoms or resolves the underlying issue, whether the solution breaks anything else, and whether or not there might be more, similar issues lurking. It is hard for someone not deeply involved in the project to do all of those things.
