That seems pretty evil, especially given the justification:
> DNT is a nice idea, but without buy-in from the entire ecosystem, its impact is limited. In place of DNT, we're adding in new, more granular privacy controls that give you control over how Reddit uses any data we collect about you.
What does it hurt to keep supporting it? It's actually pretty ironic: "DNT doesn't have total support across ecosystems, so we stopped supporting it".
Might as well, it's basically useless. Very few sites support it, major ad networks instead have an opt out [1] that nobody knows about and if you block 3rd party cookies, isn't relevant anyway. Blocking trackers remains the end user's prerogative.
I've always been surprised that Reddit hasn't had many trackers - basically just Google Analytics and Doubleclick. Especially since their parent company is so heavily into tracking on news sites.
It will be a real shame if they start gunking it up with trackers - many news sites are basically unusable without ad blocking.
