I can simplify this further
"We continue to look for ways to make the purchasing experience simpler for customers, including our current multi-year investment to ultimately shift the customer experience to one purchasing platform and a single agreement for any type of offer,"
to
'We continue to look for ways to make our licensing so complex and predatory that the confused customer shafts himself , but ultimately want to shift the customer to a single self-shafting experience.'
Note the resemblance to the mobile phone industry with it's multi-tier price structures, 'minutes' discounts, and packages. Overall this makes it impossible to compare one offer against another and simply choose the cheapest. And the customer coughs at the end of the month, because it's easier than working out exactly what was paid for.
There's no real option with a mobile phone, but if MS didn't have its huge installed user base, would its current product line really be able to compete?
