A few general thoughts:

1. Buying and playing Hogwarts Legacy sends a certain message, whether you intend to send that message or not.
2. Any guilt you may feel over sending that message is not the fault of the people who notice you are sending that message.
3. If your sole motivation is to avoid feelings of guilt, playing a different game is probably going to be easier and more effective than arguing on the internet about why your sending of that message doesn't count.
