I'd agree with the ripped off part (although I'm sure there are companies that did something similar in the past). However, I'm not sure what muscle and money has to do with it. It's not like Instagram/FB were advertising for Stories (at least I didn't see any).
Muscle/money is also equivalent to rallying resources to quickly rip off features. Let's not forget that builder (engineering/design/product) resources in small/medium size companies come at a premium.
It doesn't take a large engineering team to add stickers to a picture. I'm being facetious here, but let's be honest, FB/IG/Snap are not building a space shuttle.
