I am sure that public demonstrations would be more successful if one person would politely ask the opposing party to stop instead of marching through the city with a few thousand people.
Public demonstration are generally organized and short.
Now if you think a riot is needed in the PS4 scenario, well, okay.
I just think you are "expressing your opinion" to people that are already well aware of it, and that may even share it. It must simply be plain annoying for them. How the fact that this is via twitter makes it less spamming remains quite mysterious to me.
You're showing muscles, but everybody knows you're still a vocal minority.
It's not at all like workers going on a strike because they boss is disconnected from reality.
In the end the plans of Sony won't change, they have a much broader vision, and you'll only have wasted the time of a few people. Once again, would you like to be the person receiving your messages?
PS : I'm totally okay with hashtags, as they don't target anyone.
edit :
Who buys the majority of software/hardware on a per person basis.
I'm saying the currently angry gamers represent a small percentage of all software/hardware sales in the lifetime of the console. That they buy more games changes nothing to that.
And that isn't even considering most angry gamers right now will still buy the PS4 regardless.
