WhatsApp showed us that running a paid, low cost, privacy oriented service can be profitable.
I'd probably pay for that, again, as soon as they were completely untied from Facebook and had apologized. (Yep, they made a very public promise.)
I'd probably pay similar or slightly larger amounts for a number of other things as well (actually I do, so my point is rather that I'd pay for for stuff :)
Now before anyone thinks: "great, lets paywall all the things!" here's an important catch:
1. I'm happy to pay for my newspaper. I'm happy to buy the occasional newspaper on a newspaper stand.
I do not want to subscribe to every newspaper that anyone shares a link to, just to read one single thing that is relevant to me. I love the idea of blendle but it seems media (and my feeling is even a lot of HNers) don't get it.
2. I'm happy to pay a certain large cloud company that I don't like as much as I used to do for an increased storage quota. I'm happy to pay reasonable amounts for apps, services etc. I'm happy to pay for usage for things I use less often. I particularly like the Jetbrains model of pay-to-own (even if I personally prefer their competitors products. ;-)
I still do not want every app to pretend they are a service that I should pay a monthly fee for.
Also: I don't really mind relevant ads. The other day I actually clicked on one. Because it was relevant.
But there is no reason to track me around the web: most ads I ever clicked on voluntarily (that would be 5 - 10 for the last 10 years ;-) could probably be inferred from context: I was reading a blog post about something related or searching for something related.
Also (and here I go against many HNers), ads should preferably be injected server side.
