This seems to be a win-win where developers benefit from more work in niche areas, companies benefit by getting better developers for the things they want done, and Igalia gets paid (effectively) for matching the two together, sourcing sufficient work/developers, etc.

I don't know much about Igalia but they are worker owned and I always see them work on high skill requirement tasks. Makes me wish I was good enough to work for them.

It's a cooperative sweatshop in that sense.

And the developers own Igalia.

Just because work is 'out-sourced' to contractors does not mean it is a sweatshop....
