Although it's regrettable that Reuters' content will be harder to access, it's a positive trend for the news ecosystem to generate increasing revenue through a subscription-based business model rather than selling ads. The more money that comes from subscriptions, the more that news coverage will reflect the interests of subscribers rather than advertisers.
Most of HN crowd I'm sure can spend a few extra bucks per month to get quality news. What about not so lucky people, though?
In my mind, a subscription model for these websites is essentially a donation model.
