I think you’re massively downplaying how much of a hit this will be.

Let’s say you make $100k/year. Think about the lifestyle it allows. You’ve just been informed that it’s now going part time, and you’ll only be making $15k/year. How far does that get you?

Now, you’re expecting someone else to pay for that advertising spot, so it won’t be that bad. But who is even eligible? Microsoft’s Bing is the obvious answer, and probably DDG. The rest of the default search engines aren’t even general web searches.

Do you really think that either of them are going to pay any significant amount to be the default? Especially when most people are going to change it back to Google anyway, since these are automatically people willing to change to a different browser?

Sure, they might be willing to pay something. But it won’t be anything close to what they had before.

SuprNova was the big one for me. Everything else was either redundant (Like RARBG) or just faded away (like my Usenet sources). I didn’t have any replacement lined up when SuprNova died.

First, a massive amount of content is removed. You won’t find a lot of popular, unencrypted content these days on usenet. It’s all encrypted and obfuscated now to avoid the bots

Speaking of bots, I don’t think you realize how much of this process is automated, or how wide of a net is being used. The media corporations all have enormous collected libraries of material. It gets posted constantly to all sorts of places. This includes public torrents, public usenet, YouTube, PornHub (yes, really, even for non-porn), Facebook, TikTok, Tumblr, GNUtella, DDL sites…

The list goes on and on. Each one gets scanned for millions of potentially infringing items, often daily. No actual people are doing those steps.

Now, throw in things like private torrents, encrypted usenet posts, invite-only DDL, listings that use ‘3’ instead ‘e’ or those other character subscriptions… These require actual humans to process. Humans that cost money, and a considerable amount of it. As a business, you have to show a return on investment. Fighting piracy, even at its theoretical best, doesn’t increase revenues by a lot.

You mention revenue and breaking even, but you left out an important detail. Your time is free. They don’t have to pay $10/month, they have to pay $10/month + $20/hour for someone to deal with it. And most pirates of that level will just find another method.

Flip it around - why would you work a job, any job, where you don’t know your pay until after the work is done?

“Tipping” is rich-people speak for shifting the expense (and blame) to the customer.
