Yeah. Notice how they emphasize how the "one-time" spend on contractors will save them money. Never includes the cost of the lack of institutional knowledge, or the impact on quality, maintainability, etc. Money brain.

For a transition to open-source to be successful and permanent, manage it well. Not like this.

IMO they should also emphasize that this money can go into German (or at least European) consultants, rather than dumping 15 million on licensing costs that will go straight to Redmond, Seattle.

Of course no guarantee that it will be the case for 100% but still better. Even if there were no savings it would be better spent money.
