No, you're not alone, if you use the forum search you will find other complaining about free games, too.

Humble Weekly sale has it for $1 along with Red Faction Armageddon. People are buying lots of copies and spamming giveaways for contributor value, like tends to happen with any such sales.

The low number of entries are because the games have been bundle fodder for the last several months. They were part of Humble THQ Bundle, available to anyone who paid a dollar. They were part of the dirt cheap Amazon THQ bundle. And now they are the two games in the Humble Weekly sale. Anyone who really wanted the games by this point already owns it. Maybe even owns it several times. (I ended up with two copies myself thanks to buying both the Humble Bundle and the later Amazon pack. Humble was unfortunately a waste of money compared to the much better Amazon deal. :/)
