Wouters canceled and libeled several people including Tim Peters while increasing his influence and power. He is one of the nastiest open source politicians.
GvR isn't far behind. Two horrible people promoting each other
For a FOSS contributor, GvR always gave me the impression that he'll work on whatever when there's funding, and abandon the work/domain when that dries up. Not exactly hype+dump but no major internal drive to see those things through like someone like Linus or even someone like Jonathan Blow has.
Like his early work on programming for kids (CP4E), and all kinds of short-lived Python projects like Unladen Swallow, with the MS funded speedup work being a later example.
