In my experience, no dev/publisher has ever give us any grief [or frankly, any comment] for any pre-release review copy they've sent to the small gaming website I write for. By accepting the early copy [sometimes weeks in advance], we only have to accept the standard review embargo that all gaming/media sites get. In some cases that embargo is fully open and only states dates when reviews can go up, while some have some additional restrictions on disclosing some parts of the game. For example, embargo for FF7R review that I did stated that recipients of early copies should not openly talk or show screens/videos from the last chapter of the game. Fair enough. Those who don't want to be restricted can get review copy at launch day. And no one had a bad comment because of our coverage/score.
