The proof is right there in their own tweets, for those of us with reading comprehension skills.
In October they said they would not publicly discuss acquisitions unless and until they were done.
Then in December they said they were going to make an acquisition, in the future tense, meaning it has not happened yet. That means it is not done for those of us paying attention.
Oh look, here's the proof right here:
No public discussions on mergers and acquisitions unless and until they are done. Avoiding being labelled as promotion.
You see, they said they would not discuss anything until it was done then later they discussed something that was not yet done. That is called a contradiction.
