Eh, I'd argue it's still a business decision. It's still possible to find "true unlimited" data plans with some companies. I've got one with Cricket Wireless.
I'm somewhat dubious on the idea that their Cricket More plan is actually unlimited, but I'm pressed for time and can't read their more dense terms of service around the plan, but I'm assuming they have a congestion clause buried in there, despite what the linked FAQ claims

It works with video because all video sites automatically adjust quality based on throughput so they just figure out when you’re streaming video and then throttle. But most websites don’t automatically change image quality based on throughput and pages load more quickly and are harder to shape…
>Cricket compresses all images that are embedded in web pages in either of two industry standard formats (JPEG and GIF), regardless of the source or content of the web page or the application used to view it. Cricket strives to compress web page images to provide a high quality user experience where the average consumer should not notice a difference between the source image and the compressed image.
