Here's the deal: These people deliberately (and fraudulently) present an amorphous front.
They espouse to have no leaders, no goals, no specifics and no demands because that's all part of their strategy. If they have no leader, there's no one to target -- no on for the public to focus on; and no one to negotiate with.
If they have no specifics (no announced demands or specific goals) then there's nothing for people to take issue with or disagree with and (again) there's nothing for the powers that be to negotiate. Then, anyone can view the "demonstration" any way he or she wants view it and it can appear to embrace whatever you think it embraces.
That's why different people of different ideologies and different political stripes and socio-economic groups and support or at least sympathize with The Occupation(s). Whatever it appears to be to you, that's what it is.This is all deliberate. It's planned. It's part of the strategy to buy time, build support and slowly inch toward broader disruption and/or play the martyr card.
Again: An OCCUPATION of a public space is NOT a demonstration. A demonstration is not open ended -- and I must assume that their "permit" to do whatever it is they are doing is not open ended as well.
BTW: Pretending to be naive and/or unaware of rules, regulations, etc. and other maters about all this (on the part of The Occupiers) is also part of the whole scheme.
These people are hardly naive or unaware.
They know exactly what they're doing.
