The right to ask the developer to stop is not what the post is about. The post is about legal threats using a claim of copyright infringement, which is not "asking" by any definition.
If you're on my lawn selling lemonade, I don't have to "ask" you to stop. If I tell you to stop, you'd better get your butt off, because you're trespassing. Same concept.
Or even: if you're on my lawn which happens to be a very popular lawn and you are selling lemonade to people in a fancy mug rather then them coming inside and getting free lemonade out of a plastic cup.
