I really don't understand how the author of the parent post is still angry about this. 37s did the responsible thing by continuing to fully support the old version, giving users time to migrate (or not migrate). I think there are a lot of 3rd parties that integrate with the new Basecamp to provide time tracking. Harvest is the one that immediately comes to mind. While this might seem to not be as good as a first party experience, I would argue that it is better to use a real time tracking app like Harvest, which is waaaaay more capable than the time tracking in Basecamp Classic. Whatever criticisms you might have of Basecamp, they are certainly focused on avoiding feature creep and bloat. I suspect they agree with my assessment that Harvest et al. provide a better time tracking experience, so there is no reason to complicate their product with a (poorer) duplication of their features.
