The defendant did not "make the law available for free", he (allegedly) distributed a copyrighted standards text. Which is not law. At all.
And no, it is not incorporated into law, either. Despite what some people usually claim.
(There are a few DIN standards that are actually incorporated, but I've never come across those, I think they are used in some building construction code or whatever).
I know, I also think it's bad that there is no way to read and use standards freely (or cheaply), but the headline is totally misleading.
