I'd say the reason is because bitrot is happening faster than ever before, and if something is not being maintained and you are depending on it for a long-lived application you are going to be burned sooner or later. Granted with Microsoft this is much less of a problem than in the open-source world, but given their scattershot strategy over the last decade it's no wonder that people get jittery at the smell of something withering on the vine (especially after Microsoft stopped being up front about killing things).
