Instagram is what it always was for Facebook: a clear sign of the decline of Facebook’s original product into irrelevance while it slowly mutates into infinite town square forums trapped in valley of echoing stupidity and a less anonymous craigslist/gumtree. The Instagram acquisition was the first clear sign Facebook never could innovate it could only steal and perfect existing ideas. Now they decided that outright copying is cheaper than buying, so they copy Snapchat and now TikTok.
