Don't worry, that is exactly what they'll end up doing. Hope you have alternatives.
AT&T Uverse has instituted a 1TB monthly cap on residential internet service. Unless you also buy TV service, in which case it's unlimited. Clearly they're targeting customers who want to stream all of their TV via sling etc. with this. Now, the AT&T small business-class internet (which I've just recently switched to) is still unlimited, though it does cost more.
Charter/Spectrum has a similar "business" class service. Yes, it costs more. I get a lower contention ratio, no caps and fast state-side customer service. My complaints are poor upstream speed and frequent, brief, early morning outages when they service the network.
