Yeah, fossil fuel companies should be better regulated, and bad practices should be punished. There is no reason whatsoever to cause unnecessary damage to our world. Keep in mind that under American law, anyone can file a lawsuit, but that doesn't necessarily mean anything. This article is from 2021, are the lawsuits still ongoing? If there is proof that companies hid side effects other than "global warming", they should definitely be held accountable. For me, these lawsuits are being filed as a response to "public pressure" and most likely will result in a big nothingburger, or maybe, some small fines (and by "public" I mean climate activists).
