I did not expect that many Other. This generally means people are still favouring M43! That is surprising indeed.
Why is it surprising? It's a great system. Small and compact with great image quality.
Just today we were at a festival. I wore cargo shorts. Put the E-M10iii and 14-42EZ in one pocket and a fisheye in the other. I hardly knew they were there. I could have swapped the fisheye for the 40-150 and not noticed it and had a huge range of focal lengths in my pockets.
None of the other systems could have done that, including my Nikon DLSRs.
If not for M43 I may have looked at Fuji as the hype and constant stroking for Sony's mediocre stuff is annoying,
