A lot of my negative opinions about the release structure are just personal bias. Episode count is more negligible to me than having a complete experience, so although it's probably on par with a lot of other releases in terms of cost per episode, having to pay so much for one series over several releases isn't a release method that I'm particularly fond of, though I can understand the need to do so as you say for the majority of people.
Basically, I'd rather pay £150 for a complete experience than £500, even if the former series is only 26 episodes long vs 350+, though I get I'm likely in the minority there.
