How do you get to 2/3rds? I am not familiar with Debian's voting system, but I get just under 1/2 in favor publically supporting removal.
I define "support" as preferring an option over "Further Discussion".
According to [0], there were 420 unique voters. Using 420 as the denominator, and collumn 8 [1] as the numerator, we get the following approval voting results:
1) Call for the FSF board removal, as in rms-open-letter.github.io - 203/420 = 48%
2) Call for Stallman's resignation from all FSF bodies - 222/42 = 53%
3) Discourage collaboration with the FSF while Stallman is in a leading position - 19/420 - 52%
4) Call on the FSF to further its governance processes - 221/42 = 53%
5) Support Stallman's reinstatement, as in rms-support-letter.github.io - 52/420 = 12%
6) Denounce the witch-hunt against RMS and the FSF - 84/420 = 20%
7) Debian will not issue a public statement on this issue - 277/420 = 65%
8) Further Discussion - N/A
It does not look like individual votes have been released yet. If they were, I would like to see how accurate my assumption that no one "approves" of both his presence and absence from the board. The sum of approval for both 1 and 5 is 255 = 61%, so it seems like most of the no statement voters actively disprove of a statement in either direction (instead of simply preferring no statement)
