This wasn't a case of whistleblowing though. It is mounting up to be a case of industrial espionage using a media company posing as "bloggers" to disseminate stolen private correspondence using innuendo and fabrications* with a view to gain illicit advantage over a competitor.
So far every accusation stemming from the stolen documents has failed to prove any criminal wrongdoing and, this is the important bit, every single legal case raised so far in multiple courts has been either dismissed or ruled in favour of Benfica.
* Example: this is a ruling from the Portuguese Media regulator making clear that the bloggers produced fake documents and altered dates and details to make allegations not supported by the stolen documents, so making the case that this is not whistleblowing but an attempt to discredit a business with lies.
