Great point. I'd argue that a partnership with Twitter is amongst two equal (or near equal) parties OR one where Twitter is the smaller player. A non-partnership relationship is all relationships with Twitter that are between Twitter and a smaller organization.
It's completely asinine to have two separate policies for small kids and big kids, yet that's what we see at Twitter. Is this an example of the 80/20 rule or something more sinister? I'm not sure.
One thing's for certain: I hate Twitter's monetization strategy not because it doesn't work but because I find it distasteful.
