There was no general awareness AFAIK. I'm from Germany and only learnt about it when I went to their site to download a book I was interested in (back in 2019 I think), found out it was blocked, researched the reason, found out that they didn't actually have to block everything, got angry (partly at the plaintiffs, but mostly at PG for their "overcompliance"), then shrugged and downloaded the book from somewhere else. So if this overcompliance was really intended to "instrumentalize" their readers, like the plaintiffs said, then I guess they unfortunately overestimated their impact.
The news that the blocking has been removed was reported yesterday by IT news sites (e.g. https://www.heise.de/news/Literaturportal-Project-Gutenberg-...), but it wasn't exactly front page news either...
