The first link I get when I searched for "putty" was `putty.org` which, according to the footer: "The PuTTY project or its authors have never owned this domain, registered it, or purchased it."

Nevertheless, I can't consider relying on probabilistic algorithms controlled by 3rd parties to be a wise strategy.

Also, these days, after decades of habit building and a rise in awareness about scam-related stuff, I think people expect to see the name of the project early on in the URL, not in 7th position as it is currently.
