I don't agree that it has a "different experience" because the tools and infrastructure are there to build the entire distribution from scratch. And this was done. I've done it myself several times. Once done, this architecture variant had the complete package set available for all the official supported architectures, bar any architecture-specific packages being added/omitted. Third parties can and do bootstrap and maintain entire architectures. I can't speak for the raspbian people and their port, but it's not hard to manually bootstrap the kernel and toolchain and then set an autobuilder loose on the entire source archive.
And that's the point I was trying to make about Windows; that's exactly what you can't obtain. Be it the old NT ports or the present day ones, outside the base "Windows" release and some key products, the rest of Microsoft's product portfolio is largely missing.
I don't think they're going to really square the circle in the way linux can, having everything available because everything is open source. On the other hand, it's not inconceivable they could end up with a server platform that does offer an awful lot of Microsoft stuff as open source, which also makes available all the linux userland stuff you'd want to have. Their handicap might be that not enough of their infrastructure software has made it to .net yet, but they've shown lately that they're willing to do some porting when it's appropriate. (Sql server!)
But the Raspberry Pi is a fundamentally flawed platform, with poor I/O, binary blobs required to make the hardware function, and a community that is toxic towards free software, with its own vaguely supported distro.
An OrangePi Zero ($7) or OrangePi PC Plus ($22) will blow a Raspi out of the water any day, due to each USB port and the ethernet port being directly wired into the SOC, allowing 40MB/s per port. Plus, I can run kernel 4.10 and mainline Debian on it without any blobs, and the only things I'll miss out on are GPU support & WiFi. The VPU has been reverse engineered though, so H.264 & H.265 video works well.
I think that's a hostile mischaracterisation of the community!
