They believe, correctly, that macro-events are the culmination of micro-events, and that change begins on the personal level. It takes just a handful of dedicated people to start revolutions. Startups should know that.
There is currently only centralized, pooled, coercive funding. Certain institutions (e.g. war industries and monopolistic entities) are disproportionately backed by forced funding. Certain road contracting is also backed by forced funding. It's illogical to suggest that a conscientious objector to the war industry is therefore being hypocritical by using roads. They are, as it happens, trapped within a system where the only alternative would be to refrain from using roads, which itself is a highly oppressive suggestion and a predicament many people find worth conscientiously rejecting. The funding of roads and the funding of unethical industries are not mutually inclusive. These are the types of moral imperatives that most discriminatory and anti-humanitarian policies have imposed on people throughout history.
Wiser is the one who asks why and listens. Many things that appear hypocritical are, in actuality, the superficial understanding of a much deeper dilemma taking place.
This is a phrase that should only ever be used ironically. :/
