They're not novel concepts, but they're hard to pull off at scale. There's no technological "magic pill" here - it's just a lot of continuous improvement on infrastructure. Oversubscription makes it possible to have a 150 mbps connection for under $300/mo. Oversubscription also makes some assumptions in order to make the statistical multiplexing work, and one of those assumptions is a certain level of concurrency and bandwidth usage.
Also, keep in mind that one of the ISPs most effective bandwidth management tricks is psychological: if they make you think that data is a limited resource, people will treat it like one and use less of it. Even if they don't end up charging you, the mere rumor that your ISP might charge you more if you go over is enough to get people to at least consider the amount of data they use.

Because other content types aren't the problem: video is. Video is 70-80% of consumer Internet traffic (sorry, no source that I can share). T-Mobile can only offer unlimited video because they are taking something that accounts for 3/4 of their last-mile traffic and slashing the bitrate by 50%. They're not saying what video you can or can't watch, nor are they changing the content of the videos.
And video is only problematic because it needs to sit in multiple "buckets" at once. Generally network traffic is optimized for high throughput or low latency, but video needs a bit of both.

In fact statistical multiplexing and oversubscription are easier to do the more scale you have. The problems occur at the lower end of the spectrum.
