Did not read the article slowly and carefully, but I find your negativity disturbing.
Change, especially sudden change, in lifestyle and routine is very stressful. Plus, all of them may be adapting to working at home already, which can be extremely difficult and frustrating with lots of unexpected pitfalls. I tried to do a video class using Line. The video kept freezing and the audio also went wonky. FAIL.
And all the while, now they to multitask too? She has to do her job AND take care of her young son? That would be murder.
I could see your opinion if she or they were just a stay at home Mom...which IS a full time job in itself. So she has her other full time job, or even part time for another which pays the bills and puts food in that kid's mouth AND she has the new full time job of being a stay at home Mom with not just school cancelled but his extra-curricular activities as well. Plus he/they probably cannot even visit friends if the new rules/requests are taken into account. AND its Tokyo area mostly, so likely a small apartment and nowhere for the kid(s) to go. When I was a kid in the country nobody saw me when I was "at home" anyway because I was in the woods all day only coming back for food and drink until dusk.
Maybe you thought she was Wonder Woman? I don't know.
If she jumps off her balcony from the 20th floor can she get some sympathy maybe?
And moving on anyone with 3 small boys has my immediate sympathy already.
