In general, true.
It doesn’t sound as though this service is conventional proxying,
though. It sounds like they’re dynamically rewriting web pages to
reduce the number of TCP/IP round trips. Since a round trip via a
satellite takes about half a second, there’s a lot of scope for
speeding things up.
Even pre-fetching is still dependent on the data being cacheable. Some
sites just don't work well with any sort of proxying, and some are
deliberately hostile to it.
I have no qualms with opt-in proxying, it can have significant
advantages. But I don't care for any form of transparent proxying,
because it can be nearly impossible to avoid it when you need to.
