This thread is a mess because it hits on one of the fundamental ideological divisions between left and right. The left much prefers the idea of wise justices who do whatever they feel yields the "fairest" outcome in any given situation, with written law being more like suggestions than rules. The right prefers the idea of a neutral judicial branch that simply applies the law as written, even if it appears to yield suboptimal outcomes in any given case.
For better or worse the USA implements the right wing view. There isn't any such thing as "spirit of the law", there's only law, and judges are relatively restrained when it comes to the creative invention of new law by (mis)reading existing law.
In some parts of the world that isn't the case. The EU is notorious for writing ultra-vague laws and then allowing the ECJ to "discover" interpretations nobody had even suggested might exist at all, even if it radically reshapes society overnight. Note that FOSS Patents is written by a German guy so his expectations are calibrated based on the more left wing European courts. But this case is being held in the USA, so it seems reasonable to expect that not to happen here and for the law to be applied as is conventionally understood.
Regardless of whether you like this or not, it's clearly untrue that it's "very difficult to imagine that Google will get away with what it's done" - that is hyperbole. Google's behavior was guided by lawyers who were implementing the standard understanding of litigation holds.
