It’s like saying no one needs Dropbox because rsync exists, or no one needs HubSpot because Salesforce exists.
Not really, its more like saying no one needs another windows when linux exists. By "no one needs" i mean the world needs open source sandbox building blocks that are up to the challenges of the current age, no closed source solution can be a fundamental building block for the world to become better and more secure. No non-local building block can be at the foundation to anything that makes the world better and more robust.
No, it's like saying almost no one wants a saaszsh. Which is probably an accurate statement.
