There's also Canonical and Debian in the distro world. Elastic is still around, seemingly panicking. Docker still exists for now, but probably should have sold when they had the chance. Grafana seems to be doing fine. Rancher got by without even trying to sell enterprise licensed versions of the software, just by selling support, and was recently acquired by SuSE.

I think there are plenty of examples out there, but they're all enterprisey, not consumer-targeting. Consumers tend not to have sufficient requirements to make it worth purchasing support and licensed versions of anything bigger than Sublime Text. Businesses love this stuff, though, since open source allows them to fix things in-house and send patches upstream rather than having to wait for the vendor to get to it.
