Paranoid people have certainly suggested it - but paranoid people will suggest anything and everything!
flu is well known for jumping species, though I guess the difference this time is that mostly when you get bird/pig-flu it infects a single person and then doesn't spread any further. This one started off like that but managed to infect people afterwards, making it more likely to spread.
This one has bits of man, pig, and bird flu all rolled up together but that doesn't really make it special, or hint at it being "manufactured". Realistically I think the idea that people would release a disease like that with a hint of making money, or killing of a lot of people has to be grossly naive at best and silly at worst.
