The redirect / social button blocker with the "allow once" option is really pleasant.
Some of this money is also used to fight law-suits, keeping ad blocking legal (at least in germany [1]), something a free solution like ublock origin can not do.

The core of the lawsuit was about Eyeo's business model specifically, charging for being listed in a whitelist. This of course does not apply to uBO.
But imagine if uBO was used by 90% of all Users, so the big publishers would notice and lobby to get ad-blocking banned, there would be no one to defend it then.
Or if google took over ad-blocking by making it build-in in chrome (and of course whitelisting it's own ads).
edit: just realized you're the ublock author! I didn't mean what I said as an insult to you (like you wouldn't care to defend adblocking). I just think it might be beneficial to have a commercial player in ad-blocking (that isn't google) from time to time.
Personally I see it as a good choice. I don't have a problem with ads themself, but with aggresive or harmful ads. So educating the companys to use better ads is good for the users.
For the huge sites, a cut of the ad revenue is taken, more or less as for any other ad network/service really. The full info is here https://acceptableads.com
