From the article:

> Members of the Tor community have asked us to explain how continued collaboration with Mullvad fits with the Tor Project's human rights mission.

> Our decision followed a thorough due diligence process that involved extensive discussions with community members, staff, and the board, a staff survey, and detailed financial analysis and scenario planning.

Tor is not a democracy and doesn't purport to be. The article outlines the due diligence they have already done, and they're writing this as notice to their community, in response to questions from it.
