If you were already on the do not call list, it means nothing more for you. The same loop holes exist for banks, politicians, surveys, etc.
Anyone who took the time to register with the do not call list was already covered, and this just covers those to lazy to do it themselves. I'd expect government to soon be in charge of wiping their butts soon also.
This is just window dressing that still allows enough wiggle roon and the ability to adapt, that I do not think my phone will ring any less.
