Sure, but GP contended that > Gmail’s spam filtering is just a pretext for passing all email through a machine learning system. Sure, one possible signal emitted by that system is whether a message is spam or not. Perhaps this determination is conflated with wether the message is useful for ad targeting And well, that's clearly not the case if Google moved from doing both ad targeting and spam to just spam. The evidence is literally Google moving in the polar opposite direction from the nefariousness that they suggest.
