That is what I am suggesting should occur now that you have to pay to play the Spiral Knights expansion.
For the expansion, the following page at the steam store is tagged as a free-to-play title but also has a price listed;
http://store.steampowered.com/app/206521/
I have sent a support ticket to Valve noting this discrepancy, and suggesting that the tag be removed.
Others may choose to do the same.

I have also suggested that the page for Spiral Knights itself (app/99900) also loose its free-to-play tag, as there is now game content that can not be accessed for free, going against Valve's free-to-play policy as summarized in the FAQ; 'You are absolutely under no obligation to purchase anything from the Steam Store in order to play and progress through these games.'
If we can't buy the expansion game content with ce, earn-able within the game, then Valve should no longer recognize the game as a free-to play title.
