It wasn't DHS advice, it was a DHS binding order of removal
DHS did not issue a recommendation. They issued a binding operational directive.
> Some industry pundits see the developments as the start of a new era of so-called cyber balkanisation.
Some people use Apache HTTPD, some others use lighttpd and some others use Microsoft's IIS. I don't hear pundits complaining about that. Or recommending that everyone use the same HTTP server, for fears of balkanization (whatever that means).
Also, pundit opining is better left to those offering irrelevant comments on Sunday morning political talk shows. Technical and security decisions should be left to those who are qualified to do that. I.e. not pundits.
> It’s a long way from the lofty goal that accompanied the inception of the internet as a network to connect the computers of academics together for collaboration, innovation and information sharing.
Yeah. It was never designed to be that, and it never had lofty goals. It started as ARPANET - Advanced Research Projects Research Agency NETwork - and its development was funded by the US Department of Defense - Advanced Research Projects Agency. According to ARPA, the goal of ARPANET was to [ ... ] exploit new computer technologies to meet the needs of military command and control against nuclear threats, achieve survivable control of US nuclear forces, and improve military tactical and management decision making.
So much for the Kum-ba-ya singing and hugging.
Today's Internet is mostly a festering pile of spam - sorry, social networking in pundit terms, cyber-war and commercial profiteering of all kinds. Get used to it.
