That looks nice on paper, but I can ensure you that on the subscription page that I used, it said absolutely nothing about what you said. I triple checked on the main page, and on the links to the detailed description of each subscription option, and nothing.

Anyway, even if I didn't find the exact clause between thousands of pages of fine print, if they try to hide this information and not make it apparent and visible right away, it is clear Ferengi business.

And it has only one conclusion, fool me once, and goodbye forever. You cannot trust a company that does such kinds of moves. You do not know what else are they hiding, like the permission to legally "steal" all your work.
