Just to mention a few points:

- The title implies that Spanner is at fault for something, then the article itself admits that Spanner is totally fine.

- Then it goes on to argue that this approach can't possibly work without physical devices for precise time. However, there is no proof whatsoever. Please be a researcher and design an experiment that demonstrates a violated consistency guarantee.

- Finally, not disclosing financial relationships with products which are praised in the article is really low, and has only been fixed after this has been pointed out here. And it is not marked as a later addendum, as usual for changed articles.
