50 Cent found himself in hot water again this week after he poked fun at an autistic airport worker for his appearance and inability to communicate with the rapper. Of course, 50 had no idea, but that doesn’t make his behavior any less childish. He’s since apologized, and lawyers for the family are reportedly asking for 50 to make a $10,000 donation to Autism Speaks, an autism advocacy group.

50 hasn’t responded to that request, but another high profile donor has reportedly come forward to give Autism Speaks $10,000. That donor? None other than Martin Shkreli, the pharmaceutical executive who made quite a name for himself in 2015 after raising the price of a monopolized AIDS drug, buying and refusing to share the one of one Wu-Tang Clan album and then getting into a public beef with Ghostface Killah.

Shkreli reportedly felt a personal connection to Andrew Farrell’s story, because he has close friends and a family member who are autistic. The much-maligned investor cooperated with the family to start a GoFundMe (which we can’t locate at this time), and in the process took to Twitter to debunk a few crazies who think vaccines cause autism. Perhaps Shkreli checked his karmic balance sheet and found it was time to stop the trolling.
