1. PIR, or someone very close, seems to have lobbied to have price restriction of .org removed. My understanding is that PIR made the argument that they're a non-profit, they have no reason to raise pricing extortionately
2. This was passed, despite a large number of comments against the idea, Ethos was incorporated the following day
3. PIR sold itself to Ethos, a for profit company
The people involved seem to be moving between ICANN, PIR and private firms.
Given all these things I don't think it's unreasonable that people are deeply sceptical. Especially with the ambiguity of "no more than 10% per year" being throw around.
