The problem is likely the many references to the Durban Conference: https://en.m.wikipedia.org/wiki/World_Conference_against_Racism_2001

From the article:

NGO repudiations of the NGO Forum’s Declaration

edit

Several NGOs, including Human Rights Watch, Amnesty International, and the Lawyers Committee for Human Rights, disassociated themselves from the language of the NGO Forum’s Declaration that dealt with Israel and with Jews.[5][26] The Palestinian Solidarity Committee of South Africa reportedly distributed copies of the antisemitic forgery The Protocols of the Elders of Zion.[27]

It’s a bitch to use with 1Password. I didn’t experience downsides otherwise so far.

What does it do? Could you explain?

You’re missing the point. It doesn’t matter what you or I believe, if a person has accepted that a big corporation knows everything about them and use this as a reason not to take action or prevent them from knowing more, then the Doctorow quote doesn’t apply.

That doesn’t work for the “the big companies know everything about me anyway” line though
