Can you tell if an AI is being trained on these Lemmy instances? How would you detect it and stop it?

It’s been an unsupportable business model from the beginning. Other than android, everything Google makes is easily replaceable by some other product. They don’t have a monopoly like any of their competition that will easily sustain them. I honestly don’t believe the majority of Google Engineers actually do anything innovative anymore as most of those people left the company when their pet projects were shut down in the first round of cost cutting measures (around the time Google became Alphabet).
