The situation is worse for US users than for Europeans and PAL shooters, because I can't see anybody in the US wanting to switch to PAL mode and shoot 25p, with the interference pattern and banding under certain light sources that brings, and the loss of 60p. Constantly switching back and forth between PAL and NTSC is a ballache, especially if camera requests card format like Sony.
It may be that YouTubers are all shooting 30p and Canon is only listening to the market, but I don't really believe for a second that this is anything but a cripple to protect higher-end 4K cameras from Canon including EOS R.
Same situation on the GX7 III and new G5X II as well, only 30p and 25p on those.
Let's hope the death of 24p doesn't become contagious and other brands start doing it.
Canon set a bad example for the entire market.
