I don't think it is rumors. It was a Black Chip Poker representative that said it on twoplustwo. I don't know if it is Merge network wide thing or not but this is verbatim what he said:
P2P Transfer Update: Effective immediately, Merge have restricted our ability to send p2p transfers between player accounts.

Further, as of November 1 they will be removing all players' ability to send p2p transfers from the poker client.

We apologise for the inconvenience, but unfortunately this is a decision taken by merge, and one we were not consulted on.
The only thing that can be for sure drawn from that is that it affects BCP.
