I don't have an opinion one way or the other about Renault's possible external motivations, but I think this...

That they haven't, perhaps emphasizes the point how a mere customer-supplier partnership doesn't hold the same importance to a supplier than being their own works-team.
...sorta misses the point.
What we've seen from Renault
is a focus on improvement, and it's one not unlike the very common practice of abandoning the development of a stricken chassis after it becomes clear that resources would be better spent on the next year's design. No one, not even the great Mercedes AMG Petronas, has the ability to successfully address two tasks as quickly and efficiently as they could address one; something has to give, or else the deficit will just continue to grow.
It's obviously not ideal, and the sacrifices involved make the process painful. But, if the goal is genuine recovery as quickly as possible, it's unavoidable.
