All the best to Mr Perham for his new project (which I guess won't be Ruby software), Sidekiq is a fantastic piece of software that addresses the needs of Actual People™ and does it in an efficient and streamlined way. That being said, it is true that the model is not as clear cut as the "Full-time Open Source" in the title would have you believe. Which doesn't change the fact that there is an open source version of Sidekiq that works perfectly well, the Pro add-ons are most likely the only non-free parts and you don't necessarily need that to use Sidekiq.
