One would say

this guy's forked MIT'd version 0 will be as real and valid as version 6 of original chardet.

instead of

> Your fork of version 6 is just as real and valid as the MIT'd version 7!

Supporting for a decade is not a basis for unilateral takeover. In last 3 months there seem to be at least 3 other active contributors, any many dozens in past, who share the copyright on parts (ownership)

> nobody is entitled to this guy's pip account or GitHub account just because he rewrote the library

this guy's also not entitled to takeover what is communal, exactly in the same manner.

Someone answered it long ago in quite some details. Feel free to have a look: https://stackoverflow.com/a/11455485

You're ignoring the part where the maintainer demonstrated that version 7 isn't a relicense of LGPL work but a complete rewrite based on public domain research and algorithms. That stack overflow article is irrelevant to this situation, and again, versions 6 and before have not been "taken over" they still exist exactly as they did a week ago and are still available to anyone that wants them in full license compliance. LGPL requires the source be made available, not that the source's distribution channels never be used for something else.

Then we are back to... if this is a complete re-write, why not a new name for new code?

I guess it's futile to argue in this circular logic when full picture is not considered and argument are being put forward only for the sake of winning argument. Have a good $time_of_day.
