Which is why they should have advertised something like that. This is related to Doom only in that the music and textures are the same. I'll forgive a little negativity if it comes from someone correcting a dishonestly titled article/submission.
Yes because Go generates static binaries and requires no toolchain. Once you link a C library, you loose these benefits and cross-compiling returns to the "normal" difficulty. In addition to that, Go code may be buggy but it's safe, while linking a C library means dropping this guarantee.
So in the Go ecosystem it is actually preferred to use pure Go libraries not to loose these benefits.
