Does it really matter? You do not know how commercial software is being developed. In most cases you do not even know which language is used and AI usage is also not disclosed. You do not know this about your phone, you do not know about your appliances, you do not know how the software in your car is being made, you do not know how everything you’re using every day is being created. I’m not sure why you have other standards for open source software. And please do not tell me that you are only using open source software in your car or in the train you’re using as public transit.

And yes, there might be harm, but let’s be honest, every other company around there is doing harm to someone or the environment. And if an open source dev uses AI this is really not the fight you want to do. fight against oil companies or something like that. factory farming, the car industry, big tech and all the other industries doing real harm. Attacking the dev of Lutris is not the fight anyone should put some effort in.
