I would give you so many mod points if I had them. I actually recently went out on a couple of dates with a woman who did just the type of "time trimming" work you describe. Even the producers and directors of TV shows don't know it's happening. It's the epitome of absurd and dishonest and makes we want to burn every bit of advertising I see to the ground.
I think that presenting ads mixed in with the main content of Slashdot, albeit in a different color is BS. It's just an extension of "video bytes" in a way, which was probably a test bed for all of this (and how well has that worked out for you, Slashdot?). I should add that I've taken to blocking the video bytes content, and I will do my best to make sure that these new paid "stories" are blocked too. You claim that it's to streamline the ad experience and prevent content like autoplaying video, etc. but I'm pretty sure it's actually just a way to camouflage advertising as actual content to those who don't know better.
What do you want Slashdot? Are you not earning enough money to stay afloat? I'll happily kick a few dollar a month your way for something where I have full control to opt in or out of seeing anything and everything that I want (apologies if you do, but I have yet to see such a thing presented clearly here). But it seems more and more you're just trying to fatten someone's wallet, and that's starting to piss me off. I'm offered the options to disable ads because I "help make Slashdot great!" but I'm going to stop providing comments and/or story submissions if you keep doing things like this. I come here because of what it has been; I contribute to help make it better and because I think that I benefit from what I learn on Slashdot. The more you do stuff like this though, and the more you force changes like these, the more you are going to alienate your primary user base (who are somewhat ironically among the few people these days who know how to block the bullshit you're trying to force on them). AC above has it right, as do so many other non-AC users who have been saying the same thing: it's possible to exist and be successful without doing this.
Stop trying to monetize your community. Maybe try supporting your community and then you'll start finding some results you're looking for.
