A contributing factor to this was the early and still fairly-extant asymmetry between upload and download bandwidth. This is going away slowly, especially with fiber (e.g. Verizon), but it was typical from the end of the dialup era right up until today to have upload be perhaps 1/10th of download bandwidth. This puts quite a crimp in self-hosting anything that becomes (or is hoped to become) particularly successful.
I had a friend who was there at the start of IP-over-cable, and they were particularly excited about the promise that they would be offering symmetric upload/download performance. By the time it became a consumer product, that too had this major asymmetry baked in.
