Some enterprises have appetites for open source and others do not. Remember, there are multiple flavors of open source. Some open source projects are backed by a commercial company and others are purely community driven.
Some enterprises insist that software be installed on their own servers behind the firewall. Others prefer a cloud model where software is hosted and supported by the vendor, a public cloud provider, or another partner.
