I actually far prefer for companies to be straight up with their "Here are our hard requirements on how you use our service, take it or leave it" over the previous iteration which was "We're going to do whatever you want us to do until we have leverage and then we're going to screw you". This is exactly the pain point that reddit continually goes through where the company is laissez faire, the shit hits the fan, they change the rules and everyone screams. I'm fine downloading an App, I used the twitter App, one in one out seems fine to me.

Oh and also, the vast vast majority of the time there was no thought provoking in depth analysis on twitter. That's not what's driving engagement in these sites.
