The above article isn't very elaborate on that, but the heise one[0] cites the judges:

'Es bedürfe "einer umfassenden Würdigung und Abwägung der wechselseitigen Interessen", insbesondere der "kollidierenden Grundrechte", betonen die Richter: "Auf Seiten der Nutzer die Meinungsäußerungsfreiheit, auf Seiten der Beklagten vor allem die Berufsausübungsfreiheit."' roughly: 'One needs "a comprehensive judgement and weighing of mutual interest", especially of the "colliding basic rights", as the judges emphasize: "on the users' side freedom of expression, on the side of the defendant [FB] freedom of trade and profession".

This is a high standard that needs quite some text and elaboration to fulfil, not at all doable by form letter.

'Im Sinne des Interessenausgleichs müsste sich Facebook aber verpflichten, den Nutzer "über die Entfernung eines Beitrags zumindest nachträglich und über eine beabsichtigte Sperrung seines Nutzerkontos vorab zu informieren, ihm den Grund dafür mitzuteilen und eine Möglichkeit zur Gegenäußerung einzuräumen, an die sich eine Neubescheidung anschließt".' roughly: 'However, in the way of balancing interests, Facebook has to pledge to "inform [the user] about removal of a post at least after the fact and about planned blocking of an account before the fact, to name the reason thereof and offer an opportunity to issue an opposing statement, which is followed by a subsequent further decision and information.".'

So they are relatively explicit in how Facebook must do things and that they cannot just file the opposing statement to the recycle bin. Facebook's lawyer called this "completely impractical" (but of course he would...) because of the hundreds of daily cases.

Oh, and btw., the court that decided this is the highest regular court in Germany, setting a binding precedent for all other German courts. There are many more cases than just those two, all the others you just don't read about because everyone knows that lower courts' decisions aren't that important and frequently overturned. So even if it was just about 2 posts, this decision is important and will shape all future cases.
