No, because the Switch is a game console whose hardware is produced by Nintendo to run Nintendo approved software. It doesn't allow homebrew by default and is a closed platform, and pretty much everyone buying one knows this.

An Oculus is not a standalone product; it is a peripheral that relies on an open PC platform for its processing. If software the Oculus uses can run on any PC and the Oculus does not have a unique hardware capacity to operate the software, then the exclusivity is an arbitrary constraint.

Oculus wants all the perks of being its own platform without the responsibility or technical merit.
