I mean, C++ is designed by committee, and it's hard to deny that it's been pretty successful too, regardless of what people's opinions on the language are. Both styles have flaws, but both can be adequate if you put in the right incentives and the right people.
I'm not sure the success of C++ has as much to do with the C++ committee as the fact that there were few alternatives competing in the same space until the past decade.
I didn't say it's due to the committee, I just said it succeeded and had a committee. Python succeeded and had a BDFL, but I wouldn't say it's due to that either - lots of projects pull off the latter but not the former.
