The canadian truckers are unable to get a hold of the 21 bitcoin that have been donated to them recently
The real distinction is whether the donation went to the miners or did it go to some third party centralized fundraising platform that could be attacked by the government.
The way I understood is that there was a donation platform (similar to GoFundMe) and the donations were sent there so you can't really say the "truckers received bitcoin" because they didn't.
Besides the Canadian government didn't "ban" addresses, they banned "bank accounts" of those who sold bitcoin for fiat and the authoritarian government thought were linked to the protests.
1. Is bitcoin really censorship resistent if the government can track and ban addresses? Bitfinex hackers being tracked and caught is another example (though most people would argue that this is an example of "positive" censorship resistence, unlike the canadian truckers example).
2. Can bitcoin be both censorship resistent and transparent at the same time?
Bitcoin is censorship resistant and transparent at the same time and nobody can ban your address. They can put pressure on their own centralized places like a centralized exchange or their banks but they can't prevent you from spending bitcoin or others from receiving it.
