The suggestion wasn’t about changing branding. It was about changing one default, just like when PipeWire replaced PulseAudio or when btrfs was elected to be the default FS. The product would still be called Fedora Workstation and kept its trademarks, logos,…
To them, they have spins for other DEs/WMs and that’s enough. And why wouldn’t it be?
Who is “them”? Clearly not the Fedora community or the community-elected Engineering Steering Committee. The ability to vote on that was taken away from them by one person unilaterally declaring that. FESCO would have decided to just keep Gnome. Looks to me like that one person would not wan to take any chances that the community-elected committee might vote differently.
