No, it's not. It's a statement opposing explicit exclusion, but that's not the same as inclusion.
EDIT to make this comment a bit more useful and productive: When people talk about "inclusion" in a DEI context, they typically mean making an active effort to include a diverse set of people. Outreach programs, looking at the community to identify things which drive away groups of people, that sort of thing. It can mean cracking down on "jokes" which make fun of some groups of people, or discussions of topics which make groups of people uncomfortable, etc.
It's a very different beast from just having a policy against explicitly disallowing contributions from people based on their group identity.
