I think this is mostly due to the highly polarized political climate. California is the most populous state and it's policies frequently end up spreading to other states and therefore is frequently focused on because if it's major influence. This is similar to how Texas and Florida are in the news a lot for their more conservative policies. While there are people out there who take the time to inform themselves and make their own decisions most people are only able to parrot back talking points they hear from the news or their friends. I suspect your coworker is one of those people and probably leans conservative so all he hears all day is how California's policies are making housing too expensive and it's too "woke" etc.
