Morals are very relevant when deciding what's right and what's wrong. In this particular case, I fully support the European Commission. Note that there are laws against setting up artificial corporate structures with the sole purpose of circumventing taxes, and that's exactly what Apple did (with the help of the Irish tax bureau). The only problematic thing here is that Apple is being made an example of. There are many other companies that are doing the same. But it makes sense to handle the largest cases first.
