The question with "personal filters" is always "who makes the filters?". Because most users are not going to spend their time meticulously tuning their filter configurations. They'll take whatever defaults and go about their day. Or maybe use some popular community-developed filter configs. You might argue that the optionality of personal filter tweaking makes all the difference. But in terms of practical impact, it's meaningless. Not enough people are going to take that option to make a difference. The point is, there will always be a gatekeeper.
