While I rarely cryo if I join a round, I'd rather see people cryo than force themselves to sit through it and either AFK or play spitefully. The latter cause far more problems than cryoing ever would.
Role play is fundamentally a grand game of improv. The golden rule of improv is to say "yes". Thus, individual actors are continuously able to play off one another. Cryoing because the antags show up and do something you do not like is saying NO.
