The incentive structure for who would benefit from HBD stabilization appears to be mostly political/social.
If @hbdstabilizer is correct, those who own the majority of current influence and stake in HIVE would benefit from stability in HBD since, with upward USD pressure, it would stagnate the power of HIVE in the rewards pool, controlled by current stakeholders.
Hypothetically if a person was attempting to "overthrow" the political and social influence of current stakeholders, they would be against stabilization. This would mean less ability for power holders to enrich those close to them or close to their ambitions, further securing power or their intended social/political aims. This is completely ignoring USD influence and purely from a HIVE economy/rewarda standpoint.
One could argue the pursuit becomes an attack on HIVE itself, because it is damaging development and rewards for everyone including the "usurper". That likely isn't too far off. However, the usurper does benefit slightly by creating more pressure on the current power brokers to select their stakes wisely, to maintain growth and stability, since the usurper is comfortable collecting the same rewards rate for just holding. They have the ability to better socially pressure those ideologically similar into beneficial positions for their own benefit. It gives more opportunity to change trajectory.
This is negative focused and ultimately destructive in attitude. It is better to cooperate and mutually benefit. No it doesn't mean everyone should contribute to it. It just means try to go the path of least resistance: social convincing and argument.
