Plenty of times they aren't the same.
To be honest, I've never met a single professional who actually bought any IEEE or ISO standard.
Plus who seats at WG14 table?
Big corporations selling compilers and OSes.
The binary you are actually executing is made with your compiler, not with the standard; which is just a static human readable document after all.
Though I'm not sure what your point is.
What a strange question..
Also lots of AT&T and Bell Labs money poured into employees salaries.
And that book was very much written to describe existing implementation(s) of C.
There's also the GNU implementation in GCC that's under the GNU GPL 3 licence. Moreover, the specification itself doesn't seem to have any licencing requirements at all.
So you're absolutely right: Go is the very opposite of proprietary.
Welcome to the club :)
>Trademarks and FOSS are not incompatible; instead, trademarks are legal tools strongly aligned with FOSS principles. A trademark is an assurance that the recipient of the goods or services is receiving a product of known source and qualities. Controlling how a FOSS project trademark is used protects the community and its software, by preventing use of the trademark in ways that are harmful to the reputation of the community or the software.
Linux is a registered trademark of Linus Torvalds[1]. GNU is a registered trademark of the FSF[2]. Your definition of "proprietary" isn't shared by virtually anyone, and would make virtually everything "faux open source", including the "open source os" project you originally worried about Go being integrated into.
