- "When a provider receives a counter notice, they must forward it to the original complainant, and restore the challenged material after 10-14 business days. At this point, if the complainant wishes to keep the material down, they must file a lawsuit against the alleged infringer."

In practice, the complainant probably finds it more cost-efficient to (0) ignore your counter-notice, and (1) refile their original complaint, unaltered, restarting the DMCA process from zero. If GitHub reinstated your work, they'll simply take it right back down again, like a yo-yo.

Much cheaper than lawyers.

This is what the process looks like when you're not HN-front-page support tier.

(I'm not affiliated with these parties; I stumbled on this set of DMCA interactions while reading the previous HN story last week).
