What does Firefox pay you for piping your keystrokes off to Google? BAT is a reward for your attention; far better arrangement and exchange than what has existed up to this point. It's not perfect, but what's your solution?

> "injected affiliate links"

You seem to be a little free and loose with _facts_. Rather than exchange your data for revenue, Brave explores revenue streams which won't keep us up at night. One such consideration was affiliate links. We had a couple (quite literally a couple/few), that would appear when you typed certain crypto-related keywords into the address bar. When suggestions were offered, so too would be our affiliate option.

This solution presented a means by which users could support Brave without involving their data. Unfortunately, a UI/UX bug caused the affiliate option to appear even for a fully-qualified domain, which meant a user who quickly typed a URL for which we offered an affiliate link and mashed Enter, could unintentionally have selected the affiliate option. That isn't _injection_.

The issue was identified pretty quickly, and a patch was sent out. Guess how much Brave made from the buggy behavior before it was patched? I'll help you: $0.

You know what would be SHOCKING though? Imagine if Mozilla had tried to do something quite similar. Oh, wait… https://www.malwarebytes.com/blog/news/2021/10/firefox-revea....

> "installed their commercial VPN without asking"

This one is actually somewhat true. We did indeed ship an inert service for some Windows users. The goal was to have the VPN option be immediately available to users who wished to purchase it, as a means of supporting Brave. Details are in the GitHub issue: https://github.com/brave/brave-browser/issues/33726.

> "and leaked DNS traffic when using Tor in its 'privacy' mode."

Oh, this is one of my favorites. It's a classic story with depth, misdirection, unexpected side-effects of decisions made years in between, and more! This one is the type of thing I would have expected to read about in _Joel on Software_ many years ago.

So, we shipped a browser with a "privacy" mode, much like everybody else. But, we weren't fans of the common approach used by Chrome, Firefox, Edge, and others. Their approach doesn't really make you _incognito_, or _private_; it just creates an ephemeral account locally and basically does some file-system cleanup. We wanted something stronger!

As fans of the Tor project, we opted to bake-in support for Tor as an optional enhancement to private tabs. This would give you one extra, super-thick layer of incognito-ness. Tor Private Tabs were shipped back in mid 2018, and the next couple of years were pretty awesome. Brave users who enabled optional Tor support enjoyed a superior experience to that found in other popular browsers.

Years later—as the tracker wars waged on—some data-harvesters got the idea that they could evade detection by way of CNAMEs, giving them first-party privileges. So in late 2020, Brave shipped CNAME decloaking, unmasking more trackers than Mystery Inc., and dramatically expanding the privacy moat.

But the story wouldn't be all that exciting if it didn't have a twist, right!? Brave's new CNAME-decloaking didn't consider the Tor scenario, and performed DNS lookups outside of an existing proxy!

While the combination of these features didn't make Brave as porous as ordinary "incognito mode", it did punch an embarrassing hole in the Tor boundary: page traffic still went through Tor, but CNAME adblocking DNS lookups accidentally went out through the user's normal DNS path.

For that narrow slice of activity, Brave drifted uncomfortably close to what Mozilla calls "private browsing": https://support.mozilla.org/en-US/kb/common-myths-about-priv... ("Private browsing [in Firefox] doesn't hide your activity from your ISP, mask your IP address or location, or stop websites from identifying or tracking you…)
