Dear Luca,
the communication was good I think.
However, I don't understand the decision process. Who is the responsible person, e.g., the product manager, who eventually decided to cut WDQS into pieces?

The decision was defined together by the Search Team at Wikimedia Foundation and the people in charge of Wikidata at Wikimedia Deutschland. In particular, Lydia Pintscher is ultimately responsible for all Wikidata product decisions at WMDE.
I would like to stress how this decision was not taken lightheartedly. It's been three years that we know that Blazegraph is on the verge of failing, we wrote a playbook in case of dramatic failure,[1] and we evaluated several alternatives to Blazegraph,[2] each with its pros and cons.
While evaluating which way to go, knowing that no solution would be a "magic wand" that would magically solve all our problems - in fact, no "magic solution" exists, each comes with its load of problems and costs - we came to terms with the fact that we needed more time and the split was a harsh, but ultimately effective solution to buy some time in the transition to the next backend.
Hope this helps.
