If your ISP provides only a congested route to say, Netflix or YouTube, then a tunnel through a better connected VPN server can allow you bypass that route entirely, increasing throughput and lowering latency.

In the case where an ISP provides optimal routing, it cannot improve latency. Compression and buffering, among other things, still may offer better throughput.

True. In that case, though, the better advertising approach would be to state that directly rather than vaguely (and inaccurately) claiming a "20x" boost in download speed.
