> Background: There's a WebRTC Chromium bug that is making life difficult for us. I'd like to pay a developer to fix it, but I don't know where/how to find people.
HN has a "who is hiring" post on the first weekday of every month. You could try posting there. It shouldn't be difficult to bring someone on through a normal consulting arrangement. Lots of people with good qualifications are looking for work these days.
Doing it through a "bounty" means that you're asking people to work on the issue speculatively, with no guarantee of getting paid (PR is not accepted, someone else gets it first, etc). So FOSS bounties (unless they are quite large) tend to be seen as recognition for basically altruistic work. And who wants to work altruistically on a Google product of all things, especially if Google itself is unresponsive to the bug report?
There was just another post about someone collecting $2 million as a security bug bounty for some cryptocurrency app. The person found a bug that would have allowed takeover of the entire blockchain for that currency. It looks from https://bughunters.google.com/about/rules/android-friends/61... that Google's highest offer for Android exploits is $1 million but there are a lot of smaller ones that are still in six figures.
Of course security issues are "unknown unknowns" and are a different challenge than simply fixing a known bug in a known feature, but just the same, the above shows that getting people's attention with pure financial incentives can take some pretty big amounts. If you're really up for that and are credible, then the approach can work.
Anyway, in the case of a project with a public bug tracker, you can always open an issue and make your offer as part of it. There doesn't have to be a "sponsor" button for that.
