> Compensation is based on the collective agreement for the public sector in Germany (TVöD-Bund) and will range from €64,000 to €82,000 per year for a full-time position, including 30 days of vacation, depending on qualifications and experience.

LOL. That's €32,122 net for a full time position. And you're not even allowed to work from a place in southern Europe where you can actually live from that amount of money.

It's more like €40,000-50,000 after taxes and contributions to health care, social security and the German pension fund. Enough for a modest lifestyle in Germany. Many OSS contributors aren't motivated by money after all.
