"some of their customers may decide enough is enough and switch to another"
IMHO very doubtful.
I assume many registrants only hold a handful of names, most probably just one or two. They are probably not aware of this issue and may not have the technical nous or financial incentive to shift if they do.
Imagine a micro-business has not just paid over the odds for registration and "Domain Ownership Protection" (£24 combined) through 123reg but have also signed up to their email and hosting deals. Moving will be a major PITA just to register dissatisfaction with some guy at an organisation they are barely aware of.
I'm happy to place a substantial bet that Haworth will find a way to incentivise a small number of those with large voting influence to vote down the proposal to replace him.
