These big companies absolutely allow regulations that "hurt" them. Deere doesn't want to deal with farmers who are pissed off that emissions stuff results in a service call at a bad time and can't be overridden, or obnoxious safety stuff that make products less useful outside of their "textbook" application, or something that forces them to expensively certify their product is XYZ or something.
Buuuuut, the cost of implementing that stuff hurts the competition way more, so Deere and friends don't really fight it.
They're trading absolute market size for stronger control over market share. Less people are going to buy their products at the margin if the products are made worse. But those that do will buy it from them, so more profit.
Those are load-bearing quotation marks: you're saying the regulation doesn't hurt them, only "hurts" them. If the regulation hurt them, they wouldn't allow it.
You're proposing a binary version of "hurt", they are proposing a spectrum. If a regulation hurts company A but it will survive whereas company B, A's main and essentially only competitor stopping A from a monopoly, will go out of business from that regulation, you know that company A won't fight it.
Then it doesn't hurt company A. It helps company A. They have more money with the regulation than without.
