Let's take your argument for a moment and apply it to a different industry and see if it makes sense.
In this universe, it's perfectly identical to our current universe other than Meta being a company that makes lawnmowers. They're not the only company that makes lawnmowers, but they're popular.
It turns out though that meta has been making lawnmowers illegally unsafe, but meta's business model that let them outcompete everyone else was cutting corners on safety. If meta made their lawnmowers comply with the legal requirement for safety it'd be an existential threat to them.
Now, I ask you, should Meta be allowed to continue selling illegally unsafe lawnmowers?
