> sorry we got caught violating your license

Oh, please. Do you not understand that OP shouldn't have needed to submit a takedown request in the first place? Add the repos' license files (and NOTICE files too, if Apache!) to your site like you're legally required to, or the next time this happens it won't be a HN post; it'll be a lawsuit.

Seriously, you're playing with fire and it's not doing anything to help your brand. People already look at Vercel with disdain, and this is exactly why.
