1% water loss on earth might help turn earth eventually into Venus?

If I'm reading the following quote right and if this person's information is correct using Hydrogen to create fusion here on earth and using the oceans to supply this hydrogen (H2O) will eventually cause something like what happened on  Venus which is now 600 to 800 Degrees all the time?

begin partial quote from:

https://chemistry.stackexchange.com/questions/101757/nuclear-fusion-and-the-worlds-water-supply 

Water is made from hydrogen and oxygen. Fusion turns hydrogen into helium. Using helium for fusion is infinitely more difficult than using hydrogen. If we start start harvesting hydrogen from water then more oxygen would be release into atmosphere which would drive world temperatures down, but not as fast as water removal would lead to super heating in the thinner crust of the ocean; see Venus. Losing the oceans are a consequence all their own and I don't feel the need to go into detail of how bad a 1% oceanic loss would be on ecological systems as well as future habitation of the Human home world.

end quote.

However, if I'm reading this correctly when 1% of the water of Earth is used for Fusion in the form of Hydrogen Fusion do you get what I got which is that it will start to move the earth towards Venus?

I'm not sure this thesis is correct but maybe over time, fusion (if we are using the oceans as a power source of Hydrogen (H2O) then maybe Fusion power used in this way is only suicidal (eventually) for life on earth if oceans are used in this way?
