Its quite simple, stop buying anything made by Kraft. If this was France the whole place would be brought to a stand still but because were wishy washy brits we will take one up the gary glitter yet again and do nothing about it, and as an example look at fuel prices. I rest my case 
It isn't just France. Most EU countries are still fiercely pro their own country and its products. As I have said before I cannot ever see the day that the Spanish allowed one of their companies to be bought by Johnny Foreigner. Similarly they do not stock produce on a wide scale from other countries in particular Britain. I once talked to a French stonemason about cheese. He was gobsmacked to find out that Britain produced
cheese. you can't blame him as the nearest they get (and Spain) is Kerrygold cheese from Ireland. Otherwise it is just home produce.....
The Brits can't have a free market economy where anything goes and you can buy
anything from
anywhere but crib when another country snaps up Britains heritage and then asset strips it.
