It may be just JetBrains fault. Apple could get into trouble in EU for "dumping" their products for free to kill competitors. Making a marginal profit may cost them in terms of the number of developers, but saves the hassle of being hauled in front of an EU commission.
This is the first comment I've seen that actually makes sense. Given Microsoft got hauled in by the EU for millions (billions?) for giving away IE, simply charging a modest fee for your product provides a safety buffer to counter any such claims.
