Of course, their points of view can be different, even sharing the same roots, for example a Chinese-American living in San Francisco, other from Taiwan, from Hong-Kong and from Beijing could show different opinions, and this wouldn't be wrong.
Somebody could say a chop-suey culture, mixing elements from different nations could be offensive but I dare to say some times these created intentionally could be necessary to stop possible predjudices against the equivalent from the real life. For example in a Chinese player group the lungs(imperial dragons) are the honorable defenders against the invasion by the oni(ogre mages, from Japanese folkore), and in a Japanese group the oni are honorable warriors who defend their homeland against the possible invasion of the lungs, or the formians, whose flag is five yellow stars on a red backroom.
Culture Chop Suey is a Fantasy Counterpart Culture cobbled together from two or more real world cultures. As with an Anachronism Stew, the reasons for this can vary from case to case. It can stem from the writer's ignorance on the subject: they …

Of course Hasbro will hire cultural consultants, and this is right, but even these could suffer predjudices against compatriots from a different version. And these could disagree about the past, one saying we need more humildity and self-criticism, and other affirm the opposite, about we should recover the lost pride.
I understand Hasbro has to worry about the prestige of its brands, but several 3PPs have created settings inspired into no-Western cultures, and I don't see these suffering complains.
Of couse establishing clear criterias could help to avoid possible unitentional offenses.
The easiest option for Western players could be to read the lore of Asian IPs (videogames and comics) and creating a mash-up with the D&D elements (monsters, PC species and classes). The option for WotC is to unlock a new mini-setting within DMGuild, following the example of the Radiant Citadel, but I guess there the 3PPs are more focused into to create crunch than lore/background.
The self-censorship is not necessary.
My suggestion is Hasbro talking with Asian companies to agree some licence into D&D-Beyond. This wouldn't sell but only free packs about the lore of videogames and comics. These could be see a free promotion for their own franchises.
