You gain complete flexibility over the language, environment, and running time, whereas cloud functions have a fixed set of runtimes and hard execution timeouts. When it’s ‘I just want to run my container’ this seems a lot more appealing than K8s and arguably requires less cognitive overhead to fit your app into the Function as a service paradigm. If you already have Cloud Functions working then run with that!
