Since you mention the focus on probrewers, I've always thought it odd that the AHA is just a subunit of the BA. That limits the transparency into the organization and the autonomy of leadership.
There was a time, decades ago, where you could plausibly argue the interests of homebrewers was sufficiently-aligned with the interests of nascent micro-then-craft probrewers for this to make sense.
These days I don't really see the billionaire "big craft" brewers the BA is tasked with supporting, having much, if any, overlap with homebrewers.
