You want freedom? Try doing anything (people usually do) in any of the parks in London. You want to see anti-freedom? Try doing the same things in any of the parks in HK. It's a big slap in the face for the cries of freedom in HK. Much like the overrated fake democracy around the place, freedom is really limited to whatever... limited space you get.
When legal activities in which doesn't affect others are being restricted in public spaces, you really need to think long and hard if these public spaces need to be renamed as something else...
From Gweipo's blog, see this website regarding the Freedom Ball project which aims to change the way public spaces and parks are being managed.
Freedom is another way of saying "I want to do something which is not allowed".
