Honestly blown away by all the comments being upset that a service with real costs is charging money to cover those costs. And the weak as shit excuses about why they won't pay money for this. It's like complaining that OnlyFans exists because pornhub is free.
It's $5/mo or $10/mo if you don't want to pay for it, there's the whole rest of the internet to get free web dev content from, not to mention the rest of MDN which they host and provide to you for free.
