Voice chat isn't there to explain the strategy before the fight. Voice chat is there to communicate changes to the strategy mid-fight, to account for things going wrong (such as unexpected deaths or disconnections). Voice chat is there to make minor adjustments based on the flow of the fight. Voice chat is there to coordinate assignments, tank swaps, bloodlust and heroism.

The raid leader needs to be able to communicate with the raid. There will be raiders that need to communicate information to the raid leader, so that the raid leader can make decisions. Typing is strictly inferior to voice as a coordination tool when raiders are watching their rotations as well as their feet.

The thesis statement of this article was that a raid requires a) a (competent) leader and b) a raid that is willing to take direction. Not every raider needs to be capable of leading; every raider DOES need to be capable of being led if they are to be successful. You don't need a mic to follow directions, so long as you make sure you're never in a position where you need to communicate anything to the raid mid-fight. For you to say that you don't need to listen to the RL mid-fight, makes you the problem raider this article was written about.
