Definitely a PR stunt - it wouldn't even be possible to service an existing Roadster, as the "special tools" are not open-source as well.

One of the Tesla ones is literally a storage cart. Another is a sawed-off 26mm wrench head, the "clip tool" looks like it could be cut out of plywood or a sheet of metal in a few minutes.
