If you're talking about typical user of the average web browser, they care about IPFS as much as they care about the rendering engine - i.e. not at all.
That isn’t really applicable here though. That’s kinda like claiming we should be against Linux because it runs all the web servers. There is a difference between centralization and standardization.
I don't think the linux comparison makes any sense for this situation. Linux has very little to do with the web experience, where the rendering engine is the core of it. Linus's ability to change world wide web standards on a whim is close to non existent. Google is literally replacing the WWW network stack (a good change mind you, but nonetheless demonstrates the level of power)
It would be cool to see IPFS integrated and enabled by default on all browsers. I doubt Google would ever take the leap, but maybe Mozilla would. I also have doubt that Microsoft would but they would be more willing than Google. Anyways, I hope this can happen before Mozilla's market share shrinks more.
I would love to hear more about your privacy concerns; we have excised quite a bit from Chromium. You can read about those changes [on GitHub](https://github.com/brave/brave-browser/wiki/Deviations-from-...). We also audit our network activity to make sure nothing ever slips out. You can read about our [desktop](https://brave.com/brave-tops-browser-first-run-network-traff...) and [iOS](https://brave.com/ios-browser-first-run/) audits on our blog.
Perhaps more of interest would be an independent, third-party review and comparison. Trinity College's School of Computer Science and Statistics did a comparative review of Chrome, Brave, Edge, Firefox, Yandex, and Safari. They found that Brave was the "most private" in terms of phoning home. You can [read their review online](https://www.scss.tcd.ie/Doug.Leith/pubs/browser_privacy.pdf).
Always happy to discuss any specific concerns you may have.
