You’re operating off an assumption when we don’t have to;
The dashboard itself shows that DFINITYs vote power increased from 19.99% to 23.03%, by 15% , under this model.
Prior to this model being implemented, DFINITY cast 34.1% of the vote on motion proposals.
At present day, DFINITY casts 38.7% of the votes on motion proposals.
So yes, it is easier for DFINITY to pass a proposal now.
