No, the lesson is this:Yes lets not develop or improve anything so that value of old shit doesn't get crushed.
Don’t completely botch a product release (MDR) for 5 ongoing painful years and alienate a bunch of customers and issue endless repeated apologies, recall several things for several years after eventual release, and then, after all that turmoil, finally release the product that you should have released all along if you had known what you were doing, and completely kill the original product making it clear it was basically a giant untested beta-design flop that countless customers paid $2000 for and is now all but worthless
