What can you do about this?
You can write your local politicians, complain, call them, visit them and demand from them to stop working on CBDC crap.
IU also found interesting project called @NoCBDC that created cool stickers that are pro Bitcoin and anti-CBDC in the same time.
You can print out this stickers, share them in your local areas, send them to friends and spread the word while we have time, or you will wake up in nightmare scenario one day.
Maybe this approach can work in civilized countries, but not on the generalized corrupt ones, that is the case where I live and as I see, CBDC is already in Proof of Concept stage here. Politicians rely on the ignorance of the citizens to pass laws they want which will favour them and their groups on long run, without any kind of uprisings from the people. The conscious minority who protests is just going to be ignored by politics, since they don't really their votes to be elected. If the three powers (executive, legislative and judiciary) want to approve CBDC, they are going to do this here without any setbacks.
I hope in your countries you have more luck fighting it back.
