1. You are not unblockable. My app was removed from the chrome app store after reddit complained, no review process, no appeals, good luck even communicating with google. Installing an app not from the appstore is almost impossible for a non-savvy user. I suggest looking at a firefox app, their app story is much more democratic.
2. I think this fight is important because a lot of companies/organizations seem to be trying to establish the precedent that they own their website experience end to end, from database to the pixels on your screen. That idea taken to the extreme will lead to computers become opaque devices ala a TV, rather than the hackable playground they are now.
