For you and I, who are already committed, absolutely! But, for people getting started on the freedom ladder, I think they will evaluate each piece of software on a case by case basis. Once they have a taste of Free Software, and it (hopefully) works well for them, I feel it becomes easier to sell the philosophical side of things.
