Turns out that StyleXP ain't free afterall. It's now $20 and the version that they released last month secretly had an expiration date that times out telling you to buy. In other words, they knew they were going to start charging a month ago but didn't tell anyone so that they'd make as many skins as possible. Now they've pulled the rug out from under them.
