I agree in general with your statement. Playing devil's advocate though, since I have been there, when someone first starts learning about bitcoin, they may not be very knowleageable in terms of privacy. So, I 'll speak for myself here, saying that, at first, I knew I had to take my coins off of exchanges, so I did. But, the mistake was made... I bought some coins through CEXs because I wanted to buy bitcoin as soon as I learnt about it. I was fascinated by it. Then, I joined the forum and I started going deep down the privacy rabbit hole. This is where I decided to stop using CEXs. But, I mean, mistakes can happen. The point is, we should fix them.
