Original toot:
It has come to my attention that many of the people complaining about #Firefox’s #PPA experiment don’t actually understand what PPA is, what it does, and what Firefox is trying to accomplish with it, so an explainer 🧵 is in order.
Targeted advertising sucks. It is invasive and privacy-violating, it enables populations to be manipulated by bad actors in democracy-endangering ways, and it doesn’t actually sell products.
Nevertheless, commercial advertisers are addicted to the data they get from targeted advertising. They aren’t going to stop using it until someone convinces them there’s something else that will work better.
“Contextual advertising works better.” Yes, it does! But, again, advertisers are addicted to the data, and contextual advertising provides much less data, so they don’t trust it.
What PPA says is, “Suppose we give you anonymized, aggregated data about which of your ads on which sites resulted in sales or other significant commitments from users?” The data that the browser collects under PPA are sent to a third-party (in Firefox’s case, the third party is the same organization that runs Let’s Encrypt; does anybody think they’re not trustworthy?) and aggregated and anonymized there. Noise is introduced into the data to prevent de-anonymization.
This allows advertisers to “target” which sites they put their ads on. It doesn’t allow them to target individuals. In Days Of Yore, advertisers would do things like ask people to bring newspapers ads into the store or mention a certain phrase to get deals. These were for collecting conversion statistics on paper ads. Ditto for coupons. PPA is a way to do this online.
Is there a potential for abuse? Sure, which is why the data need to be aggregated and anonymized by a trusted third party. If at some point they discover they’re doing insufficient aggregation or anonymization, then they can fix that all in one place. And if the work they’re doing is transparent, as compared to the entirely opaque adtech industry, the entire internet can weigh in on any bugs in their algorithms.
Is this a utopia? No. Would it be better than what we have now? Indisputably. Is there a clear path right now to anything better? Not that I can see. We can keep fighting for something better while still accepting this as an improvement over what we have now.
Completely facile argument, right there in the last sentence.
YOU BUILT THE FUCKING THING. Just turn it off and go away. Tada, we now have something better: no privacy-violating data at all.
Who’s forcing you to make advertisers happy? Don’t answer that, because I don’t care. You can’t pretend to be about privacy and then build things that help advertisers violate it.
This one’s also pretty funny btw:
Advertisers don’t give a shit. They have zero motivation to fix anonymization. They’re not going to HELP us get rid of privacy violations.
I have defended Mozilla for years, because we can’t let Chrome become the only browser engine available.
But goddam, it’s getting hard to be enthusiastic about it. This is starting to get like voting for the genocidial dementia patient because at least he isn’t the megalomaniac pedophile.
Well, yes. Except for the fact that advertisers now have an excuse to try more invasive things to get to their data
That’s why a trusted third party is handling this. They care a lot, because of they fumble it they are now an untrusted third party and someone else will take care of the anonymization part
They’re going to do this anyway. As far as Firefox is concerned, it’s the browser’s job to stop them. That’s what Firefox is selling: privacy
Assuming I take this for granted, they have already fumbled it by turning on an anti-privacy feature without consent. They can no longer be trusted. Not that you ever should have trusted them because whatever motivation they have for pure moral behavior now, that will change with the wind when more VC money gets involved, or there’s been a change in management.
And firefox has ALREADY had a recent change in management, which is probably why THIS is happening NOW. They just bought an adtech firm for pete’s sake. Don’t trust other people with your data. At all.
