Yeah, just like you don't really want to have more than one company hosting text on the web. Imagine the mess it would be if there were more than one company hosting text on the web! It's a massive perk of the current system that all text that is published on the web is hosted at the web hosting company!
But, quite seriously, I think we have a massive problem on our hands if even people who frequent hacker news just aren't aware of the concepts of standards and interoperability anymore, that a monopoly seems to be perceived as the only way to achieve integration at the user experience level.
Want to have more than one TV channel with a common user interface? Obviously, all TV channels need to be owned by one company!
Want to have more than one appliance with a common electricity supply infrastructure? Obviously, all appliances need to be provided by the one electricity supplier!
Want to have more than one newspaper in the same language and alphabet? Obviously, all newspapers and their common language and alphabet need to be owned by one company!
Want people all around the planet to be able to talk to each other remotely? Obviously, all telephones and telephone networks need to be owned and operated by one company!
I'd really like to understand how this thinking managed to take hold, given that it seems to be so obviously fallacious to me.
