I’ve seen that before. Notice that what has been blurred is the key millings that may allow you to recognize the D4 keyway. Logo’s to identify the mechanism and its associated key require that the key be marked with the logo’s that apply to ensure key control coverage. While those keys have the Biaxail logo, they do not have the M3 logo. Because they are the D4 keyway they are still protected by US law against duplication of the keyway, but the www is visible beyond the boundries of the US, hence blurring.
