You're saying that Apple's 30 pin connector, introduced in 2003, was a copy of a "industry standard" that was designed in 2010?

Maybe that's why you're struggling to find a source that "directly confirms it".

The standard is for the specification of the pin layout not the plug. As all the links on the wikipedia page are broken and I can't remember the name of the plug itself, we're at a loss here.
