Sorry, but I am skeptical of your argument that Japanese companies are any less cooperative or more avaricious than companies from other countries.
I am aware of several examples that directly contradict your argument:
- JIS screwdrivers.
- Really, JIS anything.
- MSX computers.
- FourThirds/MicroFourThirds.
And there’s a practical reason for camera brands to have different mounts: different camera systems have different flange distances! You’ll even see multiple mounts within the same brand as the line evolves, as seen with the transition from Minolta/Sony A mount to E mount.
