Hackerrank runs a business which helps companies test candidates by doing code challenges.
Presumedly they don't invent every test from scratch - more likely they plagiarise existing tests and profit from them - which isn't really a problem until they start treating it as their own IP
Seems like probably someone at hackerrank added a classic code challenge to their library (FizzBuzz)
And presumedly this then resulted in their legal team/bots going out and initiating DMCA takedowns
