It's a volunteer project, they have no requirement to be 'professional'. That's basically the root of the whole issue. A hobby project is not a product, and its developers are not vendors. Free software is not a supply chain.

But it's developers do offer paid consulting as ffmpeg maintainers, which Google does pay for.

The word "unprofessional" here is muddying the comment more than it helps.

Let's just saying they're being asshole-ish, which is a problem for volunteer projects just as much as non-volunteer ones.

The ffmpeg twitter sucks.

Because we've worked as open-source maintainers and experienced the same frustrating asshole-ish behavior from companies before.
