Not the first time
In the days when people distributed software as "shareware" it was not unusual to find license terms which allowed free non-commercial use, but expected commercial businesses to pay for it (or simply not to use it).
The arrival of the open source mindset, and especially the "commercial software is evil" attitude from people like Stallman and the FSF, has led to many people releasing software as "free" without really thinking through the consequences. It's all very well to put something out there with no strings attached, either just to be 'nice', or to avoid responsibility to support it, but that comes with a price: anyone can use it according to the "free" license that you chose, and you don't get to complain later that it's "unfair" for them to make money doing so.
