I read the article - and it is apparently a fact. However, Samsung has given the usual official sounding "explanation".
I think it is a common occurrence in blogdom - people do take money, and write "reviews" etc. STill, it was bad form for Samsung to assume that every blogger would accept money and do the bidding. And it was extremely boorish to cancel return tickets, and asking for own passage back home etc.
But again, this news would perhaps remain in confines of techie circles, and wouldn't really affect Samsung.
For their part, the bloggers in question could have read the danger signals - there were plenty all along - even before they left India.
