It is the same logic as not wanting to use some blockchain/crypto-related platform to get paid. If you believe it is mostly used for crime, you don't want to use it to get paid to avoid legitimizing a bad thing. Even if there's no doubt you will get paid, the end result is the same, but you know you would be creating a side effect.

If some way of creating a product supports something bad (and simply using any LLM always entails helping train it and benefit the company running it), I can choose another way.
