This is not an "official" response, but just from me as an individual. Here's what I've been able to find out. Please take it as coming from "just Jenny" and with the knowledge that this is not my wheelhouse. I'm not officially in the loop for business development, pro products, Posit communications, etc. I could have some stuff wrong here, but it's my best effort at summarizing what I know and what I feel.
My main conclusion is that the word "partnership" is doing a lot of work here that leaves the wrong impression. Or at least allows/encourages a wide range of impressions.
I think that no money was exchanged, nor is planned to be. Nor is there some ongoing technical collaboration. My understanding is that this "partnership" means that someone who has a license for a Posit pro product can use the license to run that product in a Palantir platform called Foundry. Allowing that was related to very specific needs and requests from existing pro customers. And that's it.
So how do I feel about that? All other things being equal, yes, I would prefer no relationship to Palantir. But I can also live with a Posit pro product being used on a Palantir platform. I can accept that we need pro customers and some of those customers might elect to compute on a platform offered by a company I have issues with.
It feels like Palantir is a company who gets a lot of bad press and deservedly so. And they probably take advantage of any opportunity they perceive to get good press and announcing a "parnership" with a company like Posit is such an opportunity. I think the press release contains some boilerplate language from the Posit side that has been used many times before. Combined with the open-ended word "partnership", the community reaction is very understandable.
I hope this at least offers some clarification of what this "partnership" actuall means in practice. And conveys that many of us internally are pretty upset about the whole incident ourselves.
