I think the definition above, from the Oxford English Dictionary, doesn’t cover the whole gamut of hacktivisim. I think it also includes setting up proxies to help people within a country access things denied by their government.
I’ve always felt that hackers are not always bad.. in fact, there are some hackers who actually hack for good! And these “hacktivists” came out in droves to assist those trying to get the word out from within Iran, during their recent election.
Even average Twitter users became “hacktivists” when they changed their home city to Tehran on their Twitter profiles to throw off the scent of the authorities.
Thanks originalistrick for the suggestion of this word.
