It's the same mistake the Mozilla team did. They
completely disregarded the Windows platform. They didn't include Administrative Templates, MSI installers, and didn't integrate with Windows system settings properly such as Root CA trust lists.
OpenSSL feels like the same kind of "Linux fanboy" group that refuses to acknowledge that there is an entire ecosystem out there used by billions of people.
Not having official, digitally signed packages available on their own website is disrespectful to the millions of Windows system administrators that are forced to scrounge around the web looking for official packages.
Instead of one OpenSSL guy spending a few hours setting up a build pipeline in the cloud, scores of administrators have to go find C++ package managers, install C++ toolchains, and "build their own" OpenSSL instead.
This is one of the many reasons I steer clear of OpenSSL. This is a team that infamously wasted time maintaining support for big-endian(!) AMD64 processors, a platform that never existed, but apparently can't find the time to build a couple of DLLs for their second biggest user base.
