For consumer-facing products, I disagree. Discontinued consumer products aren't deprecated, they become retro and their value on eBay skyrockets (for example, before Nvidia killed Nvidia 3D Vision, you could get Nvidia's 3D glasses brand new for MSRP, now people are asking for above-MSRP even for used).
But for enterprise/corporate products, I agree. The sad thing is that AWS, Azure, and Google Cloud are the new VMWares, since what runs under your open-source Kubernetes cluster is a proprietary stack. Yes, you can move your Kubernetes clusters to Rancher by rewriting all your Terraform files, just like you can move all your Ubuntu VMs from VMWare to Proxmox, but both cases are cases of vendor lock-in.
And yet, everybody, from startups to big corpos, is ok with this new severe form of vendor-lock-in. Please someone make it make sense!
