So rather than clarify the new Twitter Policies, it would be more interesting to be told why they are making these changes. Everyone is assuming it's because they want to lock down their platform... & lock it down along what seem pretty moveable and arbitrary lines. Why else would they do it? I'm a casual observer, but I have been following pretty carefully, and it's completely unclear to me. So -- If it's not, they…
My guess is that they want full control. If you look at Apple it is clear that there are huge advantages in having this control. Not only is it possible to build a better and more streamlined experience, it's also much easier to monetize a Twitter that they fully control.
Think of the several monetization "experiments" of Facebook: ads, sponsored likes, sponsored posts, page offers, ecc They were been possibile only because Facebook manage the way his data is displayed across all platform.
