I agree, but IP addresses haven't been used as the main source of tracking for some time.
Advertisers learned how to use much better data points a long time ago due to AOL proxies much like the Mobile proxies a significant amount of mobile providers use today.

I don't think companies should give false hopes to people, and that is what is exactly happening here (e.g., "fixing a DNS leak will make you private and that's the only reason you're not!").
I agree with what you're saying, but I don't believe Mullvad push that narrative.
In the article, they warn that "DNS leaks may have serious privacy implications for users".
Looking at their marketing homepage, they say "Using a VPN alone is not enough to achieve perfect privacy. There’s simply too much data being extracted through most browsers."
It also seems like there's some misunderstanding about what the internet is in general here or a really bad misrepresentation ("you're not on the internet because your packet traveled over wavelength" wtf):

This statement clearly implies this is the reason that Android is currently not safe.
