Vodafone CZ have this same aggressive throttling on their pre-pay monthly tariffs with the extremely annoying feature that if you run out of data it is basically impossible to top-up unless you're on wifi because they don't exclude Vodafone CZ sites or IP addresses from the throttling! It was even worse a few years back - once you had used your data allowance you had no way whatsoever to top up at all.
