The CC-BY is the most permissive of Creative Common license series (And it's version 3.0 in this case). It's the first time that I open this web site, and I didn't make an exhaustive or conclusive research, but at a glance, it seems the site just puts the option to get a “commercial” license automatically, without taking into account that in this case, the license doesn't limits commercial usage of the work. Maybe when designing the web site, the developers assumed that all licenses would limit commercial usage and that the Copyright holder will always be interested in licensing commercial usage; clearly that is not the case. If they also do this for Copyleft licenses, then they would be spreading the mistake of confusing the freedom of works with whether they allow commercial usage, which is a common misconception; the GNU project has an essay on this.
