Sorry, the following post is totally off topic in relation to the @tuxedopuffin questions. But I would like to write some personal thoughts/opinions.
This is not totally true. If you think so, then any open source software is a test bed for any commercial enterprise. Also Ubuntu is a product of Canonical, and Canonical makes money selling support/whatever on the same distro “tested” by a whole community. Debian is a test bed for any flavor of downstream distribution. OpenBSD is a test bed for various enterprise NAS. And if you think so, also the Linux kernel is a test bed for many commercial products (also the evil Micro$oft).
If you like to see the world in that way, you are totally free.
What I think is that the whole life is a give and receive. When I started to play with computers, there where not free and gratis products (we had such often bloated freeware or shareware softwares, ok). If you wanted to use a program or an operating system, you had to buy it or… you had to be a pirate and make an unauthorized copy of the floppy disks of your friends.
Today we have the possibility to learn and work with great softwares and systems in total legality. We should thank the whole community and the worldwide movement of the free software, but also many (not all) enterprises that put money on some projects and let the whole world to legally use such great stuff.
(Disclaimer: I don’t work for any of these enterprises).
Well, also without a firewall you have less troubles… Without a password to type at each command you have less annoyances… Etc…
I tried Arch. And trust me, if you need to work, it is not the right distribution for you. If you want to tinker and you have the time to play/learn, if your hobby is customization and tinkering of dozens of options and configurations, then it could be a nice distro.
Well. One of the reason why many people choose Fedora, is that there is not proprietary stuff in the default repositories.
In addition, from the point of view of the community and of the sponsors (Red Hat in primis), avoiding legal threats is healthy in order to further a project.
You know, perhaps today we may have been all BSD users instead of Linux, if BSD hadn’t been in legal quagmire in the early '90s, who knows…
We are always in a threat: look at the recent news about GNOME.
In addition it is not so difficult to add third party repositories in Fedora if you need them.
Indeed, maybe I think that this is a false myth. For instance I’m not a developer and I use Fedora with success
