If players weren't already aware why they couldn't play on FTP, and TBH from what I've heard anecdotally from others -most just fired up Google as people do these days. They certainly do know now once the amended civil complaint & 'Ponz scheme' press release and to a lesser extent AGCC revocation hit all major news outlets e.t.c
In the UK the Telegraph, FT newspapers have continued the story today.
FWIW I seem to recall reading in the FT (or London Financial Times as you foreigners call it

) suggest that Orinic Limited was intended for the Swiss region.
re: players returning to a new site
You must remember how immediately post BF, although there was some caution and a dip at first players continued to play despite having option to play elsewhere and numbers recovered (see Pokerscout).
Although the situation has changed since the amendments to the civil action I expect a similar thing to happen but with an initial loss of some more players.
If a few of the other sites are waiting to offer good deals when a new FTP opens then it should be clear without the presence of a new FTP they wouldn't be offering these deals else they would have already made these promotions. Therefore multi-site ROW players would be wise to support a new FTP with some of their play or these fabulous promotions from other sites wouldn't be available without the new FTP presence
It should also be considered a new owner means it's kind of a new site especially once after stablilisation they start making their own mark and changes -so it's entirely possible there will be some migration from other sites to 'Le nouveau FTP'.
It remains to be seen what will actually happen, just risk and reward - if there was guaranteed no risk there'd be no reward for the investor LDO.
