is he owner all cloud mining farm ?

I doubt it but it wouldn't surprise me.
Oh, and about MineThatCloud, do not invest in that. If that's not a ponzi, then their electricity costs of 0.26 $/kWh ensure it will never be profitable. For example, AMHash's maintenance costs work out to around 0.07 $/kWh.
If you really want to purchase cloud mining contracts, stick to the ASIC manufacturers and keep clear of the obvious ponzis that refuse to provide any evidence of legitimacy, seem to good to be true, or simply don't make sense.
