Could have. This politically correct stuff I do not know anything about and am not interested in learning. To me, the dates are either BC or AD.
You might be interested to learn that the dates are the very same, the only difference is whether it is referred to as BC (Before Christ) or BCE - (Before the Common Era) or AD - (the Latin phrase anno Domini, which means "in the year of our Lord”) or CE – (The Common Era).
But both systems still use the Gregorian calendar as their starting point.

Does the usage of BCE and CE carry with it the baggage of political correctness? Yes. It is now commonly used in academia and in scholarly articles in recognition that not all people in those fields are Christians, but the dividing point between BC and AD and between BCE and CE are still marked by the accepted date of the birth of Jesus, even as some Christians along with some secular scholars refute the exact date of the birth of Jesus. The demarcation line between BC and BCE and AD and CE still use December 25th year 0 as the reference point.
And FWIW, I am aware that some, even some scholars refer to BCE and CE as “Before the Christian Era” and the “Christian Era”. So feel free to substitute that if it makes you feel better
To dismiss out of hand an interesting article just because you take offence over the use of CE rather than AD and that you evidently don’t even know the difference between BC and AD) clearly shows that you really “are not interested in learning”.
