I have the unlimited data plan for $50 each month yet cox reduced my gigablast plan to 50m download 3m upload which is completely inadequate, for 90 days because they think I am HARMING others connection in the neighborhood

If I were you, I'd send the contractual agreement of your unlimited data plan to your lawyer to look at. It is at best misleading advertising to offer any "unlimited" package and then subsequently limit you. Cox network has been a trainwreck since Covid. Wouldn't surprise me that they throttle you because you are taking too much of the network. Especially if you are in the double digit TB (10+) in a month. They might literally not have the infrastructure to support it and the rest of the neighborhood. They shouldn't offer an unlimited data plan if they cannot actually cope with these sorts of numbers.
