You payed for accessing the content the way it’s described in the ToS. I expect you haven’t read the ToS. It’s a contract. Violating that contract is piracy. There is no argueing about that. If you think piracy is morally okey then that’s your thing and your opinion that I respect. But it’s definitely piracy.
The contract states you don’t own it and they can take it away any time. So why are you stupid to sign it? Buy a physical book if you don’t like it. But there is no justification for piracy like “I don’t get exactly what I want so I now decide that I have the moral right to do whatever I want with indefinitely.”
