Not sure how this changes anything.
Their open source program [1] only grants a free 1-year Docker Team subscription. After which time the whole system is unusable. And most of those features aren't what open source teams even need which is surely just basic multi-user access.
They really should have just tightened the entry criteria for their open source offering if they were so concerned about it being misused.
