Past and history counts but the protection of people long dead is much less important. I make a difference there.
For starters WW2 veterans are not "long" dead. There were quite a few of them living around a decade ago. And I doubt you would allow to tarnish memory of your own grandparents even if they died many years ago.
And also we are not talking just about "people long dead", but also about their values and worldviews. And those values and worldviews are held by people today.
Yes, you are right, it's censorship, but not unfair censorship. I make a difference there. Normal living persons have a right not to be depicted in a negative or derogatory way. This right is much more worth than the right of some random game makers to make more money. You call it censorship, I call it illegal depiction of living persons in a negative or derogatory way.
There is a fine line somewhere. For me it's a question of decency.
Which brings us back to the question - are all
living persons have a right not to be depicted in a negative or derogatory way, or only specific
Standards that exclude things based on various metrics could be considered a form of censorship, but the implications of using the word censorship characterize the mode and intent of said censorship as having malicious intent based on the colloquially accepted meaning of the word "censorship" as used in a modern context.
Yes, modern meaning of the word "censorship" is indeed implies intentional censoring media according to one's agenda and political views and not by a standard clear set of rules, common for everyone. Which is exactly the case of Apple, who disallowes games if only specific
governments and specific
other real entities portrayed as enemies, but is totally fine with other
governments and other real entities to be portrayed as villains (see amount of WW2 games where you kill German soldiers in App Store).
