WSL has a couple of problems for us:
- WSL is far too big (many GB), Cygwin's core parts (cygwin1.dll) is
small (10MB, full useable cygwin can be reduced to 40MB)
- WSL cannot be deployed as part of a product, i.e. Cygwin can be
bundled with a product or project, WSL is completely independent
- WSL consumes lots of main memory even if not in use, Cygwin is just
another Windows DLL
- WSL requires separate admin skills, so it is much more expensive for
an IT department
- WSL is actually a VM with an OS, so it generates CVE which needs to be handled
- WSL apps cannot communicate with Windows apps
- WSL is buggy. The 9p filesystem network provider keeps crashing for
us if you try to access SMB or NFS shares
- WSL is not stable for end-user systems. It needs to be bootet, you
need to wait until its finished booting, and if you don't shut it down
it will corrupt its own filesystem. Permanent headaches with this damn
thing

Compare this to Cygwin, which is just another Windows DLL, fast and
easy to deploy and use, and the Windows admins are not permanently
angry about it
