That doesn't imply cloud computing is a hard requirement, just that a server (might be) a requirement.

In a different universe where the cloud / SAAS never took over the market, Cat-GTPurr could be distributed on mail order Blu-Ray disks or (in the worst case) a spinning drive or two, or downloaded once via bittorrent; and then hosted locally. The cost of such a distribution would be a rounding error for most big tech companies.
