Depends on the nature of the service - for dns, vpn and so on - thing you only really need one of - once chosen it makes sense - nextdns is 1$/month, backblaze 10 and i feel fine for subscribing. And not locked in in any way. I don't really need second one of any of those.
It doesn't make sense when your consumption is spread between many vendors - like news sites or streaming services or substacks. There should be option - done one time to someone on substack. There are authors I would like to send some money, but they just don't create enough value.
search engines and gpt chat bots are something in the middle - you usually have 1 + 1/2 backup. Goodle, then bing (google filter way too much some stuff), then yandex (since there torrents are not nuked). In this spot subscribing for each is too much money, but just limiting for one has real quality of life costs. Kagi seems to be somewhere here. I wish them luck - search space begs for disruption, but my hunch is that 10$/month is on the high side. On the other hand having those kind of people is valuable. A search engine for the rich will have easier time pitching value adding service.
