That doesn't necessarily change the overall mission of the organization, but definitely does give them more flexibility to offer paid options to help sustain development, should they see an opening in the future.

This is more or less taken directly from Thunderbird's website (which I think is a fair comparison): "Thunderbird operates in a separate, for-profit subsidiary of the Mozilla Foundation. This structure gives us the flexibility to offer optional paid services to sustain Thunderbird’s development far into the future."
