You could easily make the case that Facebook is copying Twitter (Vine), an American tech company that TikTok copied.
But let’s be real, there’s nothing impressive or innovative about making an Instagram clone with short video clips rather than pictures. All this talk about its magic algorithm is ridiculous. What would be impressive is if they were profitable, which they as far as I know are not. Their scalability is also overrated since other companies are doing all the heavy lifting, and they’re spending hundreds of millions on attracting users to their free video sharing app.
