Microsoft has really pushed this in the recent(?) versions of Windows 10. When it was first released it wasn't this bad, now it pretty much forces you during install to link an account then also forces you later (as you mentioned).
Yeah this is still happening in Windows 10. I reinstalled Win 10 Pro recently and the only way to make a local account during initial setup was to unplug the ethernet cable on my desktop. As long as an internet connection is up, it isn't even a hidden option.
I did a reinstall of windows pro N last week, and had the PC connected to the network. It required a few non-prominent buttons, but I manged to only make a local account. I was still caught out by the security questions though.
I suppose this might be the difference due to the N version. If I recall this leaves out some of the default media encoders to avoid some anti-trust legislation in Europe. Might be that they are slightly less aggresive with these dark patterns in that version.
