Orlens is demanding Williams give them a better explanation on why Kubica was retired. Seems like they may move forward with some legal action depending on how they feel the explanation is.
So....rock bottom for Williams?
You mean "ROKiT bottom"?
But seriously, I'm not sure what Orlen's angle is here. It was a one year deal because of Kubica, and they already announced that they would be leaving Williams since Kubica is "retiring". It's not like other teams don't park their cars to save them for future races, I guess the only difference here is Williams admitted it was to save parts and not PU elements like is usually the case. It just feels like they are kicking Williams when they're down.
Depending on what you believe, Orlen is still interested in remaining in F1 with either Haas or the Pink Panthers, but whether that requires Kubica getting a testing seat with either team is a question. If that's true, I'm not sure why they would be pursuing this matter with Williams because that's not the best look for future sponsorships in F1. If Orlen wanted to pursue this matter, they really should have done it privately.
Edit: It's not like Orlen didn't know there was a major issue with Williams before the season started. They showed up late for winter testing because the cars weren't built.
