That capitalization convention is included in the Associated Press Stylebook (https://en.wikipedia.org/wiki/AP_Stylebook https://en.wikipedia.org/wiki/AP_Stylebook); the author's use of that convention is not evidence of any broader "allegiance." (Maybe some feel that adhering to the AP's guidelines is enough evidence of bias, but I think it is imprecise to judge the author specifically for following that convention.) (I am not expressing any opinion on the broader topic(s). I only wanted to call out that the author's writing conventions may have less significance than OP implies.)
