It's not a clickbait of course, it's just that the term 'web server' and 'manage' made it easy to misinterpret the subject. Typically, by managing a web server we mean administrative tasks involved in configuring and running a multi-threaded http daemon. Perhaps "2 million web server processes" would have been better.
Even that would be confusing, as "Erlang process" != "process" for anyone that's not an Erlang programmer(or who doesn't parse "process" as the Erlang variant by default)
