I’ve felt this way for two console generations.
Some games like mario or kirby you can get away with it but 100 hour rpgs? Naw son, give that boy a personality
I do think Persona can still get away with it because it feels like you are interacting with the cast when you are hanging out with people. Compared to the 1-on-1 supports with Byleth in 3 Houses. Those were atrocious as it felt like you were watching one person talk, which highlights the issue in the article.
Ultimately, Dragon Quest has mostly been a pixelated game and before that, it was 2D. 11 was where it actually felt more alive and where the typical silent protagonist for Dragon Quest doesn't work anymore.
Ultimately, it comes down to, are you creating him a reason to be silent, and it works like Persona? If not, don't be lazy and put some effort since a bad silent protagonist can make a story driven game worse. Obviously, that doesn't excuse for creating a bad protagonist in of itself like Corrin from Fire Emblem.
