Earlier quoted context omitted.
"Personalization is just a different term for relevant results" Fine. It's not a "filter bubble", it's "excessive personalization", and it's still bad. Arguing about what it's called doesn't do a thing to change whether or not it exists, or whether or not it's a real problem.
Is it actually excessive, though? You're just assuming that it's a real problem without any evidence to support that it is.
My personal stance is actually a great deal more nuanced, which is that you can't not be in a bubble. It is mathematically impossible. Any way of slicing the torrent of information coming at you constitutes a bias. The entire idea of "piercing the bubble" is an instance of English misleading you, it's a concept without a referent. The question is not how to "escape" the bubble, the question is how do we choose our bubble?
