I highly recommend Turing's biography “Alan Turing: The Enigma” from which this story is taken. It's a great book. Very detailed and well researched. Author dives into many topics related to Turing's work like math, ai, cryptography.
According to WSJ [1] the issue was that the ads were autoplaying with sound on. Just auto playing by itself isn't considered intrusive by the industry.
The motivation behind publishing this database is interesting. It's a response to the western media using the term "Polish Death Camps", which enrages polish public. Personally I didn't think it was a big issue until I saw Obama use that term.
