Firstly, many do offer 10gb
Most of them being oversellers, and who knows, your host could be one of them too (not allegating them to be so, just expressing a possibility).
Next up, internet was meant to be free, so I find it odd for your host to lock down ftp connections to French ip's.
I mean if China would've done it, I could understand it, but we're talking about France here ?
Lastly, you might have seen on many occasions, people saying, 'Me and my wife, our love will live on forever', the next year they can't stand each other !
'Diamonds are forever', try baking it in a furnace and see how long is forever...
Besides, Mayan Civilization has forecasted Doomsday in 2012.
And many have predicted various dates. So we never know, how much time is left.
So, your host is definitely not 'Forever'.
We had a host called mwzaf which used to claim to offer things similar to this. And they vanished one fine day, I'm not saying your host will vanish anytime soon(I certainly hope they don't), but I'm just trying to say 'Nothing is Constant' , and if they claim to be Free Forever , then they're fooling you...
