Exactly, it's kinda like a PnD scheme, isn't it?
We couldn't be sure about this. But I think Litecoin developers are not directly involved in this if this was indeed a planned pump and dump scheme. Litecoin is unlike many shitcoins that are just pump and dump coins. Litecoin is certainly more than that.
Although it was a mistake on the part of Litecoin to just publish what is clearly an unverified report taken from Reuters, they showed that they haven't the slightest of intention of misleading the public with that fake news.
Yea, there is no concrete proof. Nevertheless, as a matter of fact, the fake domain that GlobeNewswire cited is a month old, it shows there are intentions about this, it might be a planned action. There must be some mastermind behind all of this.
We had to give the benefit of the doubt to the Litecoin Foundation, the Foundation also already denies it. As you say, we can't know for sure about this since all of eyes are going to GlobeNewswire, the one who started the news.
