Laws have unintended consequences.
Also I subscribe to a number of services I barely ever use, generally because I got in with an account very early on, and the price I’m paying is usually 1/5 or less of the current retail price. I do not want companies to proactively cancel my service.
“Thats Absurd!” You may say... well for about 10 years I kept my original AT&T unthrottled and unlimited plan goong on an iPhone, then iPad, until my credit card expired and the payment lapsed. Of course my account want instantly closed and my grandfathered plan unavailable.
Did I use more than 30 GB a month? No. Could i buy that plan again around 2017-2018? Nope. I was happy to secure that for $20/mo.
Do I want companies to have more red tape and penalties, such that they proactively shut down accounts from legacy plans? Absolutely not, get off my lawn.
