All those people on the roads cheering them where just holograms?
Tell me that these people cared about truckers before? They (including the cheering holograms) will go back to not caring when they stop being useful propaganda. You made that argument in regards to the homeless. I agreed that it is a valid one for any movement or cause including the convoy protest.
If you can make a sweeping statement about what people care about it stands to reason that it can be made by others.
