At least that's what they formally announced, but in particular I have my doubts that it's really a decision to favor the environment, especially considering that these are companies that do not want to lose money for anything in the world, only time will tell that is hidden behind these decisions, Anyway, I think that the solution to the environmental problem is to work to discover other forms of energy, since the existing clean energies do not manage to cover the current need, so not providing digital services and artificial intelligence to the oil industry will not be the solution, since unfortunately we still depend on oil whether we like it or not.
