'The sign said don't pee in the pool, it didn't say don't bring in bottles of pee you prepared at home and open them in the pool' is not a defence -- people should know better, and it was probably expected that some tiny number of customers would effectively ruin the 'unlimited' service for everyone was.
The responsible approach, as you misunderstood it, was to say 'Here are the T&C - we may change them at will, and shall notify you, at which point you can choose to cancel your service'.
Your pee example is not the same thing at all. There was no 'technicality' being breached by people using lots of bandwidth, they were doing so because that's EXACTLY what they paid for when the signed up for an 'UNLIMITED' plan.
A better example would be signing and paying for, a 2022 BMW, and instead getting a 2010 Kia. Sure it still drives, but it ain't the same thing.
It really is not.
