I mean, yeah, he was. Sutherland is a professional actor, sure, but unionized actors receive an increased payment for every reprisal.
For David Hayter, depending on how they view it, that would either by his fourth & fifth times playing the same character (Big Boss) or his 12th and 13th (that is likely also why he never reprised his role for the Snake Sword DLC for Revengeance, which is just a sword that talks like Snake).
There was also the whole thing of the role necessitating mocap that was more similar to professional acting, which necessitated actors more familiar with that.
A final thing to keep in mind is that for Metal Gear, English actors are not Kojima's focus. His voice cast is the Japanese cast, and his Snake is Akio Ootsuka, who voices him in every game. Kojima's involvement with the English dub was, in fact, very limited beyond wanting further script checking after MGS1 and 2 up until MGSV where mocap became an integral part of the process.
