Possibly they're "hell bent" on using the existing name because they've been using that name for their project in their github repository with their pip package that they've been supporting for a decade now. If they chose to make a new name, new package, new repo the current one would simply be abandonware. That's no different from what they're doing now, but with the added benefit of including a mechanism to inform their users of the situation.
You're acting like they've just swooped in in the last week to steal this repo out from under the community, when you have to go back to 2024 to see another person's name in the commits and to 2022 to see another person show up more than once. This one guy has been thanklessly maintaining chardet for years, decided to do a fresh rewrite and decided he'd like to use a different license now that the opportunity is here.

And you're right! Version 6 and earlier is (functionally but not actually) free of "any ownership"! It still exists in this repo and out in the world! You can still personally fork it and make your own LGPL with a version 7 if that's the world you want to live in! If you don't want to use an OSS project using MIT you still have the community non-ownership of that code!
But you're not upset that the new code is MIT, you're upset that the new MIT code is using that name in pip and GitHub, but pip is MIT and GitHub is proprietary! The parts you're mad about were never LGPL! Because reminder! This code works outside of pip! Git is decentralized, this GitHub repository isn't the source of truth! Your fork of version 6 is just as real and valid as the MIT'd version 7! Your fork of version 6 can still be called chardet and will still work and is still community owned! You never had to use this guy's repo and this guy's pip publication! And nobody is entitled to this guy's pip account or GitHub account just because he rewrote the library, the community is entitled to the software and they still have it. This is all 100% valid under even the strictest FOSS license, much less LGPL.
