No, Java SE had commercial features forever and you can't use them accidentally. You have to pass a command line switch called -XX:+UnlockCommercialFeatures. They are free for development use and as such there's no DRM, it works on the honour system. Oracle have simply started stepping up their efforts against people who were, shall we say, not able to handle the honour system.

The commercial features aren't relevant to most developers, so it's all a bit of a storm in a teacup. There's certainly no bait and switch.
