But that's alright, absolutely. But it's unrealistic that they get ALL their ships (and enough to be a threat) from the same people. Especially capital ships, which they apparently only have a dozen or so - barely enough to compete with legions of Star Destroyers.

What I'm saying is that yes, it makes perfect sense that sympathetic corporations would fund the Rebellion. However, it would make sense that they have a greater variety of ships due to the nature of the group - which is a conglomeration of many different small factions.

It would be like five different militaries banding together, but deciding to only use one type of plane while they could use ALL of their different kinds and brands of planes instead.
