No
I think Fester deserves a serious answer to a serious question.
The answer is No, but there’s a bit more to it than that, IP (Intellectual Property) law grants a temporary protection for commercial ideas that are patented.
To the degree that social media platforms use patented algorithms and/or copyrighted software they can not be duplicated.
A sufficiently motivated and clever enough person or group can often figure out a way to achieve much the same, or better results.
This is not a trivial exercise when a multibillion dollar company is trying to beat you to every improvement and alternate methods, and to patent or copyright them first.
