Agree, "customers" who use CentOS are not paying for Linux and won't pay for any other distro. Somebody has to work to provide a stable distro and supported on many hardwares, hypervisors/clouds and softwares running on top of OS. But the funny things is that usually there is a huge contradiction on people who uses CentOS on production, they are the same people who pays for proprietary software like Windows, Office, Oracle DB, VMware, etc... sometimes spend millions of dollars on these softwares, but save some bucks using a free Linux distro!! But I do respect the ones who are entirely open source, just don't think any big company besides Google for example, would have a huge IT teams to support everything

Agree! It is the beauty of open source to build it you own way. Google or other giants build their own distro as well, but they have enough talented people to maintain it

So let's recap, you don't have budget to spend on Linux but pay Microsoft for Windows and probably Office... And now you are angry for allegedly not having a 10 year support for your OS, so you can avoid some work on upgrading or migrating the VMs. I suspect you should be running VMware as well (and paying for it), instead of KVM or some other open source hypervisor. If the VMs are on a public cloud, you are paying for it indirectly as well. You may have some additional work indeed, but you saved a lot on not spending on a paid Linux distro, being Red Hat's or any other distro, therefore it should be worth it... take that into account
