When I open a new tab, I am "on task" - I have a problem that needs answering and the last thing I want is any distraction. Everything from news articles, todo lists or witty quotes is counter-productive to staying on task. It's almost the worst possible time to be shoving some unrequested content into my face to break concentration and pull me in the wrong direction.
It's not Pocket that's the problem, it's the gross attempted force-feeding (that just makes me want to try some other browser like Brave (not an endorsement, just what I personally would investigate next)).
How about, instead of "we plastered all this shit from the crap we bought onto every single browser window you henceforth open, you mindless peon!": how about they did some promo graphic and well-done animated enticement, along the lines of, "Hey! Pocket has tons of subscribers who upvote the most meaningful and relevant stories to them — how about we replace your blank homepage with the best of the best?"
But instead they're just like EAT THIS SHIT PLEEB and you know what fuck it I did just switch my default browser while typing this. :middle-finger-emoji-that-HNs-1970s-site-generator-isnt-compatible-with:
If you want the least-gross behavior, it's not going to come from a for-profit startup.
Hell yeah! Stick it to the man! Totally consume that content with a different browser!
