Because replies like this turned StackExchange into what it is today. So people stopped asking questions there and started asking questions elsewhere. https://youtu.be/IbDAmvUwo5c

Sadly some people on these other communities seem unwilling to answer such questions if they know the answer or just ignore the question if not and in turn answer with “this isn’t Reddit/stack/quora”, when it actually holds the community members that could actually answer the question that was asked.

It’s a shame really.
