Emotional? I have absolutely nothing invested in this, and I can objectively observe that Twitter are being dicks.

Also, the apologist's response "it makes business sense" doesn't offset the fact that it is a dick move.

I find it odd and somewhat worrying that so many people seem adhere to the logic "if there's a business reason for it, it's okay". The way Twitter treats the ecosystem around Twitter is quite definitely not okay, no matter what the rationale behind it is.
