The folks at Hashicorp decided to relicense Vagrant under the Business Source License, a non-free and open source license. While the packages for Ubuntu 22.04 and, I'd assume a number other distros, are still an older Apache licensed version, at some point, there will only be non-FOSS licensed versions.
Overtime, it may make sense to migrate from vagrant to Docker which, through Moby, Podman and other compatible runtimes, can be fully open source. While Docker and Vagrant are not identical in functionality, I think it's probably a doable task.
