I just don't get why silent protagonist's are still a thing in video games!

Because for many players it's easier to feel more immersed as the main character when they're silent as the player is more able to fill the gaps with a personality of their choice rather than one the developer has chosen. Voiced protagonists are imo one of the most overstated in how people make them out to be as a lot of the time we get the same generic personalities which is why I'm glad Zelda still doesn't have Link speak.
