Why were so many willing to support fidel castro and the cuban revolution

Many Cubans were willing to support Fidel Castro and his Communist regime to displace the Batista regime, as the Batista regime was extremely unpopular due to it stating that it followed Democracy, all the while showing symptoms of totalitarism, leading to the eventual overthrow by the widely popular Castro, who promised change (which occurred as the Communist Regime, which also soon fell into unpopularity).
