It is a myth. But if a particular soap is causing problems I'd stop using it. Especially since this problem is affecting other kitchen items.
OP might also want to photograph the ingredients on the back of the bottle. In the unlikely event another brand or brands cause this issue, I know I'd get frustrated if I couldn't figure out what not to buy. Or just return to a known safe brand.
The closing paragraph kind of undercuts that though. Like people may remember, but they'll think you're cool.
The takeaway is clearly to shart in public if you want people to look up to you.
