That is a valid point, but one source of carbon is not equal to another. Data centres use electricity and the biggest cloud computing providers are making efforts to use more green energy for their servers. Airplanes, on the other hand, burn liquid fuel directly high up in the atmosphere, and little effort is expended by the industry to change this. That is the big difference.
