The article does make a solid point that every claim of angered opposition from the players came long after the war. To me the part from Stanley Matthews reads a bit like fan fiction and self-tempered memories after the fact...Not a pleasant sight for sure, but when you read the story behind it, it only becomes really sinister with hindsight. It was seen as a gesture of respect to their hosts at the time, and although the players did not want to give the salute, it probably galvanised them to soundly beat the opposition.
The thing about history is you can't change it, the problem is if you don't learn from it!
I would wager the article is correct in its "somewhat of a conclusion" that it was likely not that great of a deal to the players.
