Instead, the cloud providers could offer prepaid credits/billing maximums to let individuals sleep at night. I would love to run my side project off of AWS to gain the experience, but no way I feel comfortable with a potentially unlimited liability because I configured something poorly. My joke project can take the uptime hit if it means I know that I will never spend more than $X to host it.
Overtime, bandwidth costs have gone down for AWS. What's finally causing me to think about jumping ship (surprised OP didn't mention OVH's unmetered stuff) is their upcoming pricing per month for IPv4 addresses. The alternative is proxying through CloudFlare, which I don't particularly want to do.
It reminds me of EU roaming before the regulatory cap, when a single video call close to the border could cost you thousands of Euros.
In this specific case it's more that I'm having a hard time picturing serious "cloud"-based web companies that decide "Oh yeah sure we'll just shut our site down if we get too many visitors". That would mean this feature is useful primarily for hobbyists, which are more likely to be put off by (and react like they do to roaming phone charges to) uncapped costs (and also not a reliable source of revenue), weakening the revenue argument for removing the feature.
AWS is famous for making those alerts hard to set and error-prone. Honestly, I don't understand why people (instead of large companies) use them at all.
This is a good reason to avoid Amazon and friends. They're set up to let you fail, and that makes them terrible companies to host your private products with.
You can still do it, but they got rid of the special-cased Console setting and instead provided a migration snippet to programatically control it using one of their cloud run/automation features or another.
Ah, here's the page, I guess:

Configuring a cap:

We should expect that these sort of implicit affordances are being trimmed as well, or at least that they're likely to be soon.
All that takes is a lean quarter and some MBA to coin a term for rookie mistake-windfalls, and they will come to feel entitled to revenue from it.
