Don't stream it and don't buy a new copy unless someone completely unrelated owns it now, but you can still listen to, watch, or read the stuff you loved before you knew what was going. Whatever you already owned didn't suddenly become toxic. Used book/music/movie stores exist. Piracy is always an option.
That's not to say a few people haven't managed to ruin it beyond my ability to enjoy their content no matter how much I used to love them, but there's no reason to give up something you enjoy just because you learn the person or a key person behind it sucks.
