Linux is on every Android phone. You can argue whether it's "real linux" or not, but that is besides the point with respect to filesystem drivers?
(I don't have a clue what does Android actually use for filesystem drivers, but I would _guess_ it's just Linux down there.)

Yes, and almost all consumer routers and quite a lot of other random pieces of hardware. Hence the billions of users.
How many of those pay for upstream maintainers?

"Yaffs" or "sparse" (which is just fancy ext2). https://source.android.com/devices/bootloader/images ; most Android kernels will also have exfat so they can use SD cards and USB sticks.
Is it? The kernel has a billion users who pay $0 for it. Most of the work is done by volunteers still. Oracle and RedHat have a few people looking at it full-time, and then Linus himself. This patchset is maintained by a third-party, Paragon, who also have an NTFS-for-Macs solution.
Hence:

Also I see the new polite kernel is going well: https://lore.kernel.org/lkml/YO8LOKR%[email protected]...
