Blogs are probably not a good example. There are so many useful services people are used to have for free on the internet, which will need to be paid without ads. Most of those could be subscription-based though. As for blogs—IMO articles that are written for money aren’t blogs, they are just old-school magazine articles that happen to be on the internet. So having them in a subscription-based closed platform seems appropriate.
