FTC? What about the Federal Trade Commission? I know they don't act on individual letters, but if enough people wrote to them, maybe they'd get involved. After all, this is sort of a bait & switch where they advertised unlimited usage and now want to cap. Also, they're charging people for a service and then limiting their use of that service to a tiny fraction of what it's capable of. That seems like a clear case of false advertising to me.
In my case, I'm going to be switching to Optimum Online, which doesn't currently have caps.
I'm also confused by all the people claiming that they'll just get business class service with another ISP. Cablevision told me that in order to get a business account with them, you have to actually prove that you have a business by providing a tax ID number.
Are they just the exception and every other ISP lets you sign up for a business account regardless? Or are people planning to register their own company just to get the business service?
