I'm sorry but that's gaslighting in the face of literally being shown the payment page that shows otherwise. "5x more usage than Pro" and "20x more usage than Pro" cannot be reasonably interpreted in the way you're doing. It doesn't matter how much you preface it with "I don't think it's straightforward".

If their legal team in fact did, they'll have said "yup, that payment page won't fly if you'd get sued in Germany/Australia/anywhere with remotely decent consumer protections" and Anthropic just decided to roll with it anyway as they did while breaking millions of websites' ToS, pirating half the world's books, academic papers and more. As the chance they'll actually get sued and receive meaningful punishment is negligible.
You're either incredibly naive, are doing similar things and justifying it, or have a personal stake in this. There's no other explanation. You can look at my comment history and see that I'm generally nice and don't comment in this manner, but you're leaving no other option as this can no longer be framed as good faith.
