Genuine question: how did the IBM acquisitions of Red Hat and HashiCorp turn out?
For Red Hat, there's no longer an official "public" distribution of RHEL, but apart from that they seemingly have been left alone and able to continue to develop their own products. But that's only my POV as a user of OSS Red Hat products at home and of RHEL and OpenShift at work.
The argument has been made that the real value of RH lies in the people working there. And if IBM were to interfere too heavy-handedly, those people would just leave, and RH would become basically worthless.
Well, there is CentOS Stream:

And Fedora is still the upstream of RHEL, nothing changed there.
I migrated our company off Terraform to Pulumi as a direct result of the acquisition.
We moved off HashiCorp's Terraform Cloud when they tried to hike the price 100x on us, although that was technically pre-acquisition I think (it was their move to resource-based pricing). In talking with our account manager, they basically said they only really cared about enterprise accounts, and that migrating away would probably make sense for us.
HashiCorp also changed their licenses to non-open-source licenses, but again I think this was technically pre-acquisition (I think as they were gearing up to be a more attractive target for an exit).
