Going from level 2 to 3 they go from INTERACTIVE to RESTRICTED as well as add MITIGATION_EXTENSION_POINT_DISABLE; in detail that first change restricts clipboard, handles and global atoms, and I suppose the remote mstsc audio playback is done through a handle.
Taking the headline literally, yeah, that isn't going to work; it would've been better if it read "from the age of 2", or something that doesn't make it a "one lesson and they know it" event.
@DavidPostill I don't think this is about changing mind about gender, but I think it's about starting off a person's life with a broader mind about gender.
If a child were born in a LGBTQI+ world where cross-dressing is the norm, that child would just as well be confused if an individual would ask him to dress as M or F alone unlike the (girl)friends.
Most children are already unconsciously introduced to gender at home and at school. A father and a mother, brothers and sisters, (girl)friends, teachers and so on. They however aren't unconsciously introduced to people from the rest of the gender spectrum (or the lack thereof) or LGBTQI+ or other folks. And that's what a company like that is trying to change, even if they don't have enough resources to do it with enough effect.
People cannot be "aware" or "understand" something if they are never introduced to it. So, at some point you will have to introduce them. At such young age, there will be a small effect but it's probably so minimal that the event alone isn't going to change the awareness or understanding of the child. Repetition however could have an effect, even if it's just opening up the child to the existence of it. Not necessarily to what it means or understanding it.
Education doesn't have to be "aware" or "understood" in order to have effect. If someone warns me about something, but I don't understand what that person is trying to make me aware of, I can still end up remembering the warning when I'm more aware and the time is right or perhaps too late for it to be understood.
