I think this is companies making something annoying blaming it on EU privacy laws and then they thinking people will be against these laws in other countries because of the inconvenience.

Same strategy of companies doing things like putting “Contents may be hot.” on hot coffee and encouraging people to make fun of the McDonald’s Hot Coffee lawsuits. People think it was a joke when it was McDonald’s deciding to keep coffee extremely hot since it last longer, they saved so much money on coffee they could easily pay people off who got 2nd and 3rd degree burns because of the extremely hot coffee. But then one elderly women got severely burned in the groin area and the jury got so angry they awarded her a couple days worth of McDonald’s coffee profit. Don’t let companies do this type of thing!

You could get a pelvic exam while unconscious without knowing it happened. Some states have put limits on it, but then they can bury it in the T and Cs you sign and do it “technically” with your consent and not tell you. So unfortunately the privacy and dignity you think you have from the medical system isn’t as good as you think.
