Parabon is the one specifically listed in the link, yes. That's who it seems they specifically partner with.
My wording was not good, my point was more it's not as easy as plug-and-play with DNA (assuming they even have the correct DNA or enough of it etc etc) thank you for clarifying.

Your point is well-taken that genetic genealogy is not going to work in every case and the result is not always the end-all-be-all. It has to be confirmed through additional testing and ideally, confirmatory evidence.
