Restrictions on Expressions in the Japanese Version

On November 18, UBISOFT Japan reported that the restrictions on bloodshed in Assassin's Creed Valhalla were "due to the fact that it did not pass CERO's review"; however, on November 19, CERO responded that it had nothing to do with the restrictions on bloodshed, and an hour later, UBISOFT Japan corrected the report, stating that it had turned out to be a problem within UBISOFT.
This was clearly an attempt by UBISOFT Japan to lie and shift the blame for removing the bloody expression to CERO.

Furthermore, five days after declaring that it would investigate the issue, UBISOFT Japan has remained silent.
In the meantime, a patch has been delivered to Valhalla that removes the restriction on bloodshed to all but the Japanese version, and Japan has been left alone.

Is this a sign that not only UBISOFT Japan, but UBISOFT as a whole is neglecting and discriminating against the Japanese market?
