That's kind of missing the point. The article is up in arms that companies which only want to spam you with legitimate products (in a product category similar to whatever you signed up for) won't get to do so, because of those bad actors, the multi-vertical spammers and scammers. OP is complaining that the industry brought this upon themselves by failing to self-regulate and stop the bad actors in time to avert regulatory attention.

The reality of course is that all text message spammers are bad actors, just less bad than the worst of the worst. It is probably is true that failure to self-regulate is what brought this down on the industry, but the industry as a whole deserves it and everyone will be happy to see it gone, except for the unscrupulous handful who make a profit off of it.

The article defends parts of spammers as legitimate industry that for now remains legal in USA.

Hopefully it will change.
