Wow Dave. Thanks for the links to the lawsuit. Fascinating. I didn't know about this. Since the original email, I actually downgraded from Spectrum cable 300 Mb/s to ? maybe it's 200 now ?, anyway it's $20 a month cheaper. And decreased the "smart queue" limits to 80/10 Mb/s.

I do not know what to do about it. It also irks me that as a
