This is a nonsensical new gTLD in my opinion.
Tools.Free? Free.Tools? Which sounds more natural?
I can't put anything in front of .free that makes sense (that is generic and not a long tail exact match). The only model I can see behind this is Amazon opening up free .free domain names to use and test with AWS/EC2 or the like, before emphasizing the importance of upgrading an instance (EC2 micro in this case) to a paid one and offering another gTLD that Amazon owns and fits the customers' business as an upsell.
Edit: Hands.Free, Hassle.Free, and some others... but limited to a select few.
