For those who are interested in the science, here is some more to read.
A transitioned male expert was the one who was putting up alerts about this, not the two people who carried out the treatment.

However, the woman’s breastmilk has not been assessed yet, so we don’t know if it has the same mix of components as in milk from new gestational mothers. This means the practice cannot yet be recommended, says Madeline Deutsch at the University of California, San Francisco. She says she can see the potential benefits of breastfeeding, but that the long-term impact of this milk on the baby – including on subtle measures like IQ – is unknown.
Deutsch herself is a transgender woman with a six-month-old baby who is currently being breastfed by Deutsch’s wife, who was the gestational mother. “I am very sad not to be able to breastfeed her and at the same time I did not consider doing this for the above reasons,” she says.
This was February 2018. I have not seen anything to prove that any in-depth studies have been released since to counter this expert's opinion. And there has been plenty of other threads since this that where these studies would have been posted by activist posters.
So, there we have it. A transitioned male, Associate Professor, Family Community Medicine, is telling the world that this is not advisable until further research.
And this is key too:
After three months of treatment, this increased to 227 grams of breast milk per day. Once the baby was born, she was able to exclusively breastfeed the infant for six weeks – during which time a paediatrician confirmed the baby was growing and developing normally and healthily.
Although significant, this is below the average of around 500 grams that a baby consumes by the time the it is 5 days old. After six weeks, the woman supplemented her breastfeeding with formula.
So.... for how many weeks did this infant receive half the nutrition it needed? This male only supplemented the feeding regime at SIX WEEKS!!!
And this was supposed to be monitored surely. It was an experiment. Why was this allowed!
