I don't think the argument that corporations threaten free speech holds water.
We disagree. I think that corporations present a greater threat than the government. With the government, we at least have the constitution and some sort of influence over how it behaves. Not enough, but some. With corporations we have none. And nearly everything we do is in a corporation's control at some point or another.
I have an iPhone. It comes with a user agreement that specifics how I can use the phone. If I don't like it, I can get another phone and/or another provider.
I don't have to have an iPhone. I don't have to use AT&T.
In the US, your choices of providers is extremely limited -- is it three nowadays? The smaller ones simply resell the service of the larger ones so they don't count. You can get another phone, sure, but when they are all behaving in the same fashion -- as they do -- then this choice is illusory.
And you do have to use AT&T. If you use the internet or telephone service of any sort, the odds are overwhelming that AT&T is handling your communication as some point in its travels, even if you aren't their direct customer.
Using tools to get around restrictions set up by the government (as in China, etc) is NOT the same thing as getting around restrictions placed on a device by the manufacture.
I think they're exactly the same thing.
I think I see where we differ. You see a difference between corporations and government. I think that they have effectively merged and there is little functional difference, except that corporations operate with far fewer safeguards. Corporations do the things that are illegal for the government, and vice versa, but they work hand in hand. The end result is the loss of liberty overall.
