Most photocopiers aren't on the internet and even if they are, the essential risk and impact attached to failure is far lower than that of a business PC running XP.
I don't see how the Apple one even maps to the XP question. The problem is with support of an essential piece of software being discontinued.
Google Wave was free and never sold or supported as a piece of business software as far as I know. Apart from that, the Wave protocol is open and you were able to migrate the content to open alternatives at the time.
Windows XP is an essential piece of software to many, replacement of which is neither trivial nor free. It's almost exclusively used on machines that frequently (or continuously) require internet access and the software didn't come for free in most cases. You can call OEM versions free, but we know that's not exactly true.
The article seems to make the point that, unless MS extends support, it's only fair (and possibly legally enforceable) to make MS share the source with parties that want to support XP and offer assistance to such parties. Or, just release the source outright.
Social media simply haven't matured to the point where it makes sense to standardize interfaces and infrastructure. Since all of them are allowed to use proprietary interfaces, there is no chance of integration and people are forced to move to the same network to find each other. As soon as I'd be able to read your Facebook post on my Google+ and you'd be able to read and respond to my tweets from your Linkein account, that need goes away. Stuff like RSS was a nice try, but that only carries the content, not the entire service.
But I don't think it will happen anytime soon, at least not without government interfering and I don't think the times are very conductive to that. The reason I say that is the battle for the app space. Suppliers need their proprietary protocols, so they can force you to use their apps and that's one of the ways to control what services and advertisements reach you. Ask yourself: why do we have protocols like XMPP, but do we still need Whatsapp, MSN, ICQ, Facebook Messenger, Telegram, Google Hangouts, etc. etc.? Again, the protocol doesn't effectively carry the service, but that doesn't mean the services shouldn't support the standard. The companies providing these services have too strong an incentive not to standardize, that outshines any and all incentives that might cause them to.
If the research shows that relaxing, avoiding stress and using your brain to think about imaginative things is healthy - say so. I'll happily increase the time I spend fishing and soaking up sun at the beach while reading a scifi novel.
None of that stuff has anything to do with religion per se though.
