Drew DeVault @sir

Let me translate today's blog post from Mozilla for you:

"We're going to model your behavior and sell categories of users to advertisers, then put their ads in your web browser"

@sir thanks. Apparently, they don't put it on their blog's homepage. Sneaky.

Anyway, according to https://help.getpocket.com/article/1142-firefox-new-tab-recommendations
all the personalization is done clientside, and no private data is sent from the browser to the pocket service.

@Wolf480pl right, but it still does what I described in my toot

@sir hmm... yeah, they can model behaviour of users who have telemetry enabled. And they can categorize them, and let the advertisers choose which category they want to show their ads to. But they have no way of ensuring that an ad is shown to users in the category it was meant for, from what I understand.
