Too late, the hive mind which is $GOOG has already shown that it will do as it pleases; "hopefully" good [when convenient], otherwise whatever is profitable even if it is evil.
Can't say I blame the $GOOG; this is an inherent problem with huge organizations -- the meta consciousness which emerges vastly undermines any altruistic desires of individuals.
