Author here. Thank you for your earnest concern. I'm a pretty risk-averse person and I take lots of pains to address those contingencies for all of my digital services.
I agree with you and imagine many others do as well. I think you are right it's about time I draw a line in my own personal life as well. No more Chinese manufactured goods for me. In fact, I think I will go ahead and get rid of what I currently own.
If you really care, reach out directly to the merchants you buy from. Tell them you used to be a loyal customer, but you won't buy from them again until they stop carrying products made in China. Get your friends and coworkers to do the same, and keep the pressure on. If they go for it, follow through by rewarding them with your loyalty, and broadcast that win as publicly as possible. Talk about it, hashtag it, whatever. Organize.
Changing individual consumption habits rarely amounts to much more than virtue signalling.
And don't toss your existing stuff. You already paid for it, so it's not helping China anymore, and throwing it away doesn't hurt them. If anything, selling it to someone else reduces demand for new products (by exactly 1 unit).
