Browsers fall in to the 'things we need to ship but the source being closed isn't a competitive advantage' of huge software corps (Mozilla being an outlier).

I listed artist tools because that's the thing I have first-hand experience with and I'm sure others here do as well but it's faaar from being limited to that.

List superior OSS alternatives to things like SAP/Dynamics/Salesforce or CAD like SolidWorks/AutoCAD. Where are all the OSS banking systems ? Every industry I've seen has their own specialized tools that cost big $ and has stuff that took years to purpose build, the sort of thing that just isn't viable under OSS model. Industrial control applications, and let's not even go to heavily regulated stuff used in medical devices and such.

I'm not the one who's tunneling here, there's more software out there than dev tools, browsers and server OSes, very little of it is OSS, even less can compete on quality.
