This always comes up in these threads and I always wonder if the commenters ever actually used Usenet.
DejaNews isn't and never was Usenet, it was an archive, and Google Groups was just another Usenet client. Google Groups embrace-extend-extinguished Usenet as much as Gmail embrace-extend-extinguished email, and it got some cachet from having historical posts.
You can still use Usenet as much as you could 20 years ago, and while it was nice a decade or two ago to be able to browse historical threads in google groups, now the Internet Archive has an excellent Usenet archive[1] so we don't have to trust a giant corporation with ADD to hold onto history for us.
I don't get your point; because google did that to e-mail. By using gmail or their paid product through g-suite, you get to be in the high QoS lane for e-mail delivery and get through their spam filter.
Google Suite and Gmail are not the only ways to get through spam filters, and since when has latency been an issue? Do you know what "extinguish" means? Because that does not sound like "extinguish" and only barely scratches the surface of "extend".
If anything, Gmail's spam filters are absolute shit, judging by all the random spam that blasts through. It's a colander at this point.
