big player + (standard) linux desktop may well be coming, but that means losing the semi-anarchist bazaar mentality. Will the standard be gnome or KDE or XFCE or ...? If gnome, version 2 or 3? Firefox or chrome as the default browser (or derivatives like waterfox or plain chromium ...)? AI integration?
The moment you're developing for people with no IT experience and no CS degree, you're going to have to make tradeoffs like Microsoft or Google or Apple have to make today, and somehow deal with the "curl ... |sh" problem.

The places you mention are already receiving huge doses of industry funding funnelled through the Linux Foundation. Honestly, it looks like the standard is going to be KDE. Even microsoft is copying it for their next DE: https://www.webpronews.com/microsoft-windows-ripping-off-kde...
Why does there need to be a standard application for everything? Is there a default pencil vendor? A default printer vendor? Paper? Car manufacturer? Taxi company? Just let people buy/get whatever vendor/application they like. I rather see more interoperational standards.
