How many Snapchat clones does it take for Facebook to lose its self-respect?

Facebook staff presumably don't join up because they want to clone its biggest competitor, but still the company keeps churning out embarrassing copies

It must be getting hard to walk into work at Facebook with your head held high. You roll into the campus in your Tesla, waltz over to your desk, and sit down, head full of ideas as to how to make the social network better for users and advertisers alike. Then a notification pings up on Messenger. It's Mark Zuckerberg himself! The boss is speaking to you! What could he have to say?

"Clone Snapchat a bit more. Thanks, Mark."
