It’s static hosting. If they change their terms, it couldn’t be any easier to switch. I switched most of my Netlify sites to CloudFlare Pages in like 10 clicks each. The whole point of having a static file is that they’re super easy to manage.

Worst case scenario you pay a few cents to host on S3 and stick any free-range CDN on it.

I categorically refuse to use any non-static hosting for static content. Your shared hosting runs code and can be compromised, especially if you host multiple software/sites on it.
