That depends on who you mean by "the BBC".And why should the fact that it is inconveniant for International broadcasters be of any concern to the BBC?
It' not like NBC/ABC/CBS etc... take into consideration the same inconvenaince when it's a US show airing in the UK.
BBC 1, the channel, shouldn't care.
BBC Wales, the producers of the show who are partially dependent on foreign sales for their budget should care. Their production budget is supplemented by the sales to foreign broadcasters. The producers are already facing a cut in the portion of their budget they receive from BBC 1; they can't afford to annoy international broadcasters and lose that money too.
