We shall start this with a quote from Sir Tim Berners-Lee,
I was lucky enough to invent the Web at the time when the Internet already existed - and had for a decade and a half. We must understand that there is nothing fundamentally wrong with building on the contributions of others.
Here we shall quote the Mozilla Manifesto,
Individuals must have the ability to shape the Internet and their own experiences on the Internet. And so, we can infer that contributing to the open web, can protect our own individual experiences on it.
