And yes you are right some btc got seized as it traveled through companies amd corporations. If youhad send monero through coinbase it would have gotten seized too.
No one would know who donated to the truckers. People could donate without fear of having the donation publicly traced.
There would also be no connection to the donation once deposited. Only that some trucker is depositing a large sum.
