If this and Reddit are going downhill, where will we look for our tech questions?! (/s, there will always be others)

I got an Odroid HC4 last year and put Armbian on it, with 2 HDDs in RAID1 via mdraid, and can connect to it using either SMB or NFS. Works great, and since it can run Docker containers nicely I use it for pretty much all my home server needs.

The thing is that in the eyes of the general populace (and regulators) it's not "just a Google thing" since Chromium is open source and a majority of browsers use that. So the argument is that most browsers will implement anything Google does and make it a de-facto standard.
