Everyone else basically abandoned these technologies, even Jackal hasn't been doing a lot of cloning since he returned, mutants are the ones abusing that shit and to the point everyone is Ben Reilly know, and that's why people got annoyed I guess lol.
Save for that one time he made a bunch of Ben clones, I thought Sinister only cared about mutant DNA.Hell, Doctor Stasis, the alleged "real Mister Sinister/Nathaniel Essex" working for Orchis, could just offer humanity their own version of the Krakoan Resurrection Protocols, as they were derived from the mutant Sinister's massive archive of mutant, human, and nonmutant superhuman DNA.
