>In the football tapes example, I don't think there is anything deceptive happening, because everyone understands that other teams are doing this. However, if it were explicitly against the rules or implicitly against established norms to review other team's tapes, doing so and not telling the other teams is deceptive and wrong.

I agree. The implicit context is that it is in-bounds to investigate your competitors through their public-facing offerings, even if they try to stop you. You don't have to stop competing just because they say please. Through an accident of law (the CFAA was enacted before it was possible to get home internet service), Lyft was able to make this illegal. Lyft is trying to block public information from getting into their competitor's hands. IMO, that's the anti-competitive activity here.
