The amount of armchair quarterbacking here is wild.

That's bullshit. The FFmpeg devs were well within their rights to even send a DMCA takedown notice, immediately, without asking nicely first.

This is what big corporations do to the little guys, so we owe big corporations absolutely nothing more.

They gave Rockchip a year and a half to fix it. It is the responsibility of Rockchip to take care of it once they were originally notified, and the FFmpeg dvelopers have no responsibility to babysit the Rockchip folks while they fulfill their legal obligations.

Deadline and reminders? They aren't teachers and Rockchip isn't a student, they are the victims here and Rockchip is the one at fault. Let's stop literally victim blaming them for how they responded.
