Depends on exactly what it is that a project is objecting to. For example, here's Nura:

> AI tools have several ethical issues. They require an unreasonable amount of energy[1] and water[2] to build and operate, their models are built in part with heavily exploited workers in unacceptable working conditions[3], usually without consent from or compensation for creators of the source material[4] and oftentimes causing DDoS attacks against FOSS infrastructure in the process[5] (which in turn force the deployment of challenge-based protections and increase cost and complexity of self-hosting for everybody[6]). Furthermore, they are being used to undermine labor and justify layoffs[7]. These are harms that we do not want to perpetuate, even if only indirectly.

If you really believe that AI tools are automatically unethical because they destroy the environment, harm workers, and constitute an attack on FOSS infrastructure, then it doesn't really matter how the tool is being used. If you just don't want to see code quality decline, then it's probably not a problem.
