They are just salty because if “Lego” becomes a true noun, they won’t be able to trademark it anymore.
Just like Google is salty about “googling” becoming a verb.
I am not a lawyer, but I remember reading about this stuff, so I am like 70% confident it’s correct.
In this case, the lawsuits are necessary to keep the trademark. If they didn't take legal action against people using the term "Legos" to refer to the bricks, they could lose the trademark. To avoid having your trademark turn into a generic term, you HAVE to take legal action to enforce it (in the US)
Not a lawyer. I can just say that they did this. In this example to a German guy having a pretty big Lego related YouTube channel. I assume you can in fact sue people for advertising products with your company name if the products are not by your company.
Edit:
I can only give you German articles about it. But Google translate should be fine to translate the page to English I'd assume. For example this.
