What does Open Source inspire you ?

3 words to define it

Open Source

In production and development, open source as a development model promotes a universal access via a free license to a product's design or blueprint, and universal redistribution of that design or blueprint, including subsequent improvements to it by anyone.

Generally, open source refers to a computer program in which the source code is available to the general public for use and/or modification from its original design.
