I don't see how it was misleading. The scientific co-operation was stopped, just as they said it will be, and it took three years to re-negotiate, without it ever being certain that the negotiation will be a success.

And the UK remains an "associated country", allowed to participate but probably excluded from decision-making (a guess, it doesn't explicitly say in the article, but the UK now has the same status as countries like New Zealand, Ukraine, Kosovo or Israel).
