Can't people just compile their own version sans-censorship?
Either way, per the developer's post, you can in fact just flip an about:config switch to disable the addon blacklist (not sure if this would also leave you susceptible to actual malicious addons); it's more of an issue of compliance budget/trivial inconveniences, and the implicit message of the action. (Note how the developer is very insistent about referring to AdNauseam as "malware"; if we go with the conventional definition of malware as being harmful to its user, this may paint Pale Moon as perceiving the website and/or ad network operators as being its clientele, rather than the person using the browser.)
