MH370 was flown by a boeing-777 which are around 73m in length. The plane located in that satelite view is around 30-40m in length, roughly half the length of a boeing 777. On top of being a fraction of the size of a 777 it also appears to be in 1 piece which would make no sense as we have found chunks of the 777 that flew MH370.

On top of that if there were a plan on the ocean floor at that location then the water would obfuscate the view of it so much that all you would see it a slight outline and potential discoloration with its surroundings, if you saw anything at all.
