Personally I believe these reality shows are for publicity and just for minting money and fame and do not have any value at all.

But most shows don't have any 'value' apart from giving the viewer enjoyment.. the world would be a boring place if it wasn't for entertainment.. having said that tho if they feel that the content in BB is too 'adult' for their country/culture nothing wrong with moving its slot imo..
