That's true - Raymond Hill, the uBO developer, doesn't accept donations or payment for his software. Truly a legend. I'd 100% donate to them if they accepted donations.
The meme is about Adblock Plus though which does have a paid tier. I prefer uBO myself, but if you are stuck with Safari then it's a legit option.
Yeah, I have a terminally racist relative and was trying to explain to her why we should look after refugees. I asked her if her neighbor's house burnt down whether she would invite them inside and offer them some shelter and comfort, and she agreed that "of course" she would. Then I asked about if it was someone from the next street over, and she immediately became hesitant about it. Sometimes I think as a species we just never psychologically evolved beyond living in a tiny village and fearing anyone we don't know personally.
