This is no hysteria.
Depending on where your company is located the sueing risk is really high. E.g. in countries like Germany there is a whole industry which lives from sueing companies and people and I can imagine that GDPR will open a whole new sueing market there.
In other countries like Austria you get first warned and then sued on big GDPR violations which is a much better solution.

From a German perspective not much has changed: The core concepts "as minimal data collection as possible" & opt-in for more, the right to ask which data a company has about you and the right to make them delete it are established law in Germany since at least 2009 if not 1983.

Not as per the law. The law explicitly states that option for judicial remedy exists. The article is the opinion of a lawyer based on current practice, but this is not what the law actually says.
