@ Draugnar
I don't see your complaints as very different from these:
* I have to take the bus to get to work, so when the local government that runs the buses raises the rates, that's not voluntary, and I shouldn't have to pay. I was riding this bus before the rates went up and no one asked me if I minded.
* I have to take a taxi to get to work, so when the private corporation that owns the taxi company raises the rates, that's not voluntary, and I shouldn't have to pay. I was riding this taxi before the rates went up and no one asked me if I minded.
* I have to drive to get to work, so when the vehicle tax goes up, that's not voluntary, and I shouldn't have to pay. I was driving before the tax went up and no one asked me if I minded.
* I have to drive to get to work, so when gas prices go up, that's not voluntary, and I shouldn't have to pay. I was driving before the price went up and no one asked me if I minded.
* I have to get a heart transplant to live and I can't afford it, so I should get it free or for a price that I can afford. I've had this heart my whole life, and hearts aren't voluntary.
* I have to use the Internet to perform my job, so my employer should provide me with an Internet connection. I was doing this job before everything went online and no one asked me if I minded.
* This factory has to stay open if I'm to perform my job as an auto worker, so the government should bail out GM. I was doing this job before GM went bankrupt and no one asked me if I minded.
* I have to use MySpace to perform my job as a record company promoter, so MySpace shouldn't adopt intrusive policies. I was doing this job before all the bands went on MySpace and no one asked me if I minded.
* I have to use MySpace to stay in touch with all of my friends, so MySpace shouldn't adopt intrusive policies. We were friends before they went on MySpace and no one asked me if I minded. People need friends, like hearts, to be healthy; having friends is not voluntary.
* I have to use Facebook to stay in touch with all of my friends, so Facebook shouldn't adopt intrusive policies. We were friends before they went on Facebook and no one asked me if I minded. People need friends, like hearts, to be healthy; having friends is not voluntary.
* I have to use phpDiplomacy to play Diplomacy with all of the best players, so phpDiplomacy shouldn't sell my spare CPU cylces to Plura. I was playing phpDiplomacy before kestas struck a deal with Plura and no one asked me if I minded.
Of course, these are all different from each other in some ways, but all of them amount to
* Things used to be one way, and then they changed in a way that I don't like. I can't avoid what changed without disrupting my life, so it's not voluntary. I was involved before things changed and no one asked me if I minded.
The example with the heart is the only one where the change is a threat to your life, and it's also probably the only one that you [you being the generic person who makes any of the complaints above] had a lot of control over. Any of the others you could avoid by changing your lifestyle, to a greater or lesser degree.
And in many cases, you were asked if you minded, but you probably didn't know about it. Just like kestas had a thread about Plura before it started here even though most people didn't notice it, local governments in the West today usually hold hearing about things like red-light cameras and bus fares even though most people don't notice them. Private corporations usually don't ask everybody; they're more likely just to take a marketing survey that you probably weren't part of, or they might not even do that. The more despotic governments also don't ask.
I'm sympathetic to all of these complaints, more to the ones (like the heart transplant) that are more disruptive to your life and less to the ones (like Plura at phpDiplomacy) that are less disruptive. And I'm upset by the circumstances of all of them, more to the ones that you had less control over (like Facebook's policies) and less to the ones that you had more control over (like the health of your heart, probably). I'll want to help you if I'm sympathetic to you, and I'll want to fight your oppressors if I'm upset by what happened to you, and those are not the same thing.
Sorry, this is long and maybe not very coherent, but my point is this: There is not a clear-cut division between what is voluntary and what is involuntary. Every decision that I make has the potential to affect you, and the other way around.
