I mean, that's just a side effect of being popular. In the 2000s, Windows was the no. 1 vector, which Apple kept riding the coattails of with their "no viruses" slogan until macOS became popular enough to be targetable and they had to eat crow. Right now, if you give me a random device, chances are the way I'll jailbreak it is through the random fork of WebKit installed on it. Everything with mass distribution eventually becomes the vector.
