It was stated that a Social Networks Sentiment Analysis widget is going to be realised, which will gather the opinions of public and key persona in it. I wonder whether it is legal to use their names in a widget without a consent to the processing of personal dataa and also using their intellectual property (posts written by them) without some other kind of legal consent, especially with commercial purposes. How this process is going to be organised?
It is legal - the data we gather is from public posts (we wouldn't be able to gather it otherwise), so it isn't much different from, for example, taking a screenshot. Even if such problem arises, we can easily disable displaying the posts themselves, and only show aggregation. But it shouldn't come that.
