What I do not understand about the decision to change it into a subscription model is the timing (and pricing). With the (predicted) failure of NXG, NI should lay low and try to save as many customers as possible from running off scared. Looking at the numbers and seeing how much money they threw at NXG it seems as if they think; well we need to cover that cost...
What they should do is conclude that they need to seriously change (revert?) how they run their business (especially the LabVIEW development projects). The true cost of NXG will continue to rise by causing damage to their brand; unless they *simplify* ownership, *lower* the price, increase the work to recruit new (starting with students) and keep customers -AND invest the required amounts into developing a proper "NXG" (it is the foundation for the ecosystem that makes NI great, the cost of it has to be divided on the whole system, not just the SW itself).
When that work is well on its way, and only then, they can think about subscriptions (the SSP solution is much more customer friendly though) and increased prices.
