I respect your position but it doesn't sound like you've worked for any company that's decided to "buy in to the ecosystem" for any sufficiently large ecosystem. Get all your data in DataDog and try to leave. Build your business on IBM and see how agile you are in 25 years. Same goes for pretty much any large enterprise software, even the free ones. Good luck leaving git. Good luck de-kubernetesifying someday to a higher or lower level of abstraction. And good luck getting the procurement department to approve your exception to not use the #blessed vendor for just your org. What happens is, everyone does that and then spends 20x more money on 5x vendors and then the other 15x is trying to integrate them all so you have a coherent business. My experience has been, service contracts are a great way to feel a false sense of security and burn cash until you need service, and then they're a great way to sit on a phone call watching revenue burn while you say "they haven't gotten back to us yet" until they say "yeah it looks fine on our end, sorry."
