I am merely pointing out that if I want to see a medical expert privately, I choose to see someone who is on the relevant Specialist Register.
Well that is your choice. There are many GPs who have specialist interests or additional training and who work privately.
And even within specialists, doctors have their own areas of expertise. There are a lot of gynaecologists, for example, who do not treat many menopausal women and who would not regard it as their specialist area.
Dr N makes no secret of her qualifications as you would see if you viewed some of her videos on her website. No one is invited to speak at a major conference like the week long BMS Menopause conference if they are 'dodgy'.
And- as Bellaciao says- the real 'villains' are those people who promote numerous herbal or other types of supplements, or devices like magnets where there is no actual evidence they work - and- moreover, evidence from organisations like the Roayl College of Gynaecologists, saying they don't work at all!
Given only 15% of women use HRT, and the rest either put up and shut up, OR spend a huge amount on products that do nothing, if you want to question people's vested interests, start with the vitamin companies, shops selling them, and the prolific adverts in women's mags and online.
