(Seriously) I wonder to what extent a cause is that the internet is US-dominated - because US (& Canadian) television is just like this too. Opaque and colourful channel logo that spins and barely fades, and advertising that pops up over the programme while it's playing!
If that's your norm on TV, sure, why wouldn't a web page work like that? It baffles me just like OP, but no more than it does on television programmes.
