Yes it's sad that there are too many MORAFs and other high ranking players that resort to dirty play. I have seen many use the tank glitch to bomb hangers, or carriers and they don't care, it's all about winning to them.
But really, how do you get any joy from using a glitch that essentially allows you to cheat? Where is the joy is just beating up on noobs, or spawnkilling?
They usually justify their actions by saying that it's a WAR game and all is fair in war (except the rules of engagement, etc.) In essence, they really don't care, they want to do what they want to do, and since people rarely get banned, they feel there won't be any repercussions to their actions, so they will keep doing it.
These people probably act the same way in their real lives, which of course makes this world not necessarily a nice place to live.
