Is uncensoring models easy and does it reduce quality?

I want to work with some content that is copyrighted. I know there are uncensored models on HF, but not sure if those are very legit, so 2 questions

1. Are the uncensored models on HF as good as the equivalent quant original model (from unsloth/bartowski etc)

2. Any "standard" plug and play script to uncensor a model?

Thanks
