The feedback loop is shit as well. Out falls a broken pile of shit for a CTP. No one accepts any feedback. It hits RTM, no one accepts any feedback. Two years down the line, the same bugs are open.
You should hear the partner reps wanting to cry when you report a bug in something that you NEED a fix for and are paying support for. You get fuck all other than a registry fix or a hack even if the mainline product is falling to bits across a thousand or so users (which is what happened to us).
Money where the mouth is as well. Typical shit:
https://github.com/Microsoft/SCVMMLinuxGuestAgent/issues/2 -> ignored. Regularly hoses our new VMs deploying windows on SCVMM.
https://github.com/dotnet/cli/issues/3093 -> fuck you go away we're just going to take your data unless you set a magic variable even though no one wants to give it away as indicated by the ticket and there are bugs in the configuration and it causes people massive audit problems.
