Also: When served from a CDN like your link above, popular CSS like Bootstrap had a decent chance of _already_ being in your browser's cache, so despite downloading more initially you'd come across sites using the same version that meant _no_ delay downloading CSS for it.

Isn't this outdated information? https://httptoolkit.com/blog/public-cdn-risks/

> Most importantly: cached content is no longer shared between domains. This is known as cache partitioning and has been the default in Chrome since October 2020 (v86), Firefox since January 2021 (v85), and Safari since 2013 (v6.1). That means if a visitor visits site A and site B, and both of them load https://public-cdn.example/my-script.js, the script will be loaded from scratch both times.

It was (and still is) never a good idea to hotlink to an external dependency.

Most developers know better than to hotlink to an image because it might one day return a completely different image (and potentially an unsavory one) yet they casually use external code dependencies.

It is also why the Dependabot(sp?) that has become so popular among devs makes me nervous. Something automatically updating your dependencies is a recipe for disaster.
