How did this stop you from deploying your own tile server with your own style?
And second - it did not stop me from doing that, but it was extremely difficult, and took months of effort. I built a tool to set up a server with all the components required to download the data, load it into PostGIS, style it with Tilemill and generate and serve tiles: https://github.com/stevage/saltymill
So I find your comment quite disingenuous.
