I've been using Haskell "at work" on my side projects (which involve other people and a live website, not just toying around), and I'd say that having learned it has impacted the C that I write in my day job. I wouldn't say I'd wasted the time, with or without an impact on my C code.

No, I know what you mean and I've run into that. I take people don't use/write Haskell regularly and claim to understand it less seriously for this reason.
But people that I think got something out of it seem to be benefiting. One is a startup CTO that was using Clojure before - he's ship-of-theseus'ing his way out.
Could also be a failure to admit they wasted their time, because of sunk costs et al.
Not meaning it as snark -- it can always be a valid hypothesis when we're talking about people.
