Losing your entire online identity because you didn’t pay on time is an absolute show stopper for an enormous number of people.
Most people are not tech people. They do not know or car, or even care to know, about the details and importance of maintaining and protecting an online identity. They won’t remember to update payment details until things start failing. They won’t check their email frequently enough to notice before this happens. They will ignore text messages, either assuming they’re scams, spam, or unimportant.
People also have a mobile phone number with a plan they have to pay for. I don’t see why a domain should be any different, and it isn’t actually that different in my country.
Another 25% had their bank balance go below zero in the past year. And that number is worse than it sounds, because it doesn't include people who have selected to have transactions fail instead of put their balance below zero. https://www.consumerfinance.gov/data-research/research-repor...
The biggest impediment is probably that most people aren’t willing to pay (say) $10 per month for a domain and email hosting like they do for streaming services, because they’re used to email being free. So they remain at the mercy of the big providers.
But I can at least encourage the HN crowd here to move to independent services and to use their own domain.
