480 > 720p upscaling = why?

I only ask this question, because I've had a few times of mindless surfing at www.stage6.com (stream HD in DivX), and also the odd time when I've tried downloading HD copies of movies I own and love.
Anyway, in these times I've found that people have upscaled 480p > 720p sometimes even 1080p, and I just ask 'why?'
What is the point? It's the same quality with a bicubic resize, and maybe some smart algorithm to make it look better, but overall nothing worth increasing the file size by xxx%.
Basically, I downloaded an HDTV rip of the Matrix (which I own in multiple formats), but it's clearly an upscale job.
Thoughts?

None really you have kind of answered your own babbelings really.

There are a load of uploads on that site, where people have taken a rip from a PS3 that's upscaled something to HD.

you admit it does look better, but apparently not good enough to justify the download for you, but perhaps there are people with fast enough connections where the larger download is worth it.

It just looks blurrier. I'm sure there are good reasons, like people who's non-PC hardware upscales badly or something.
I was more interested whether people generally think that upscaling is the way to go, given the small quality increase (which to me, just seems like a bicubic resize) and the large file size increase.
I don't really see the benefit, and wondered if anyone else does. Anyone here actually take time to upscale their videos?

Say for example you have a jpg that is 50 px by 50 px and someone says make that 100 px by 100 px it is now blurry cause you can't put information in that isn't there. Same applies to TV.

'People' upscale their movies for the exact same reason 'people' can't see the problem when asked to Photoshop a web photograph into a poster-sized print - they simply don't understand the underlying restrictions in technology. They've been sold 'new whizzbang HD thingamajig' and by god, they're going to use it.
The sad part is, they've just spent all that money on a new player & TV and they probably don't even notice the fact that the file they've upscaled is no better than the DVD original. I suspect that, once you've taken compression artefacts in to account, the actual quality will be significantly less..
