What is Ubuntu‪?‬ M. Sean

What is Ubuntu?
Ubuntu is an open-source, free, and free operating system based on the Linux kernel. You can download Ubuntu and install it on your computer using a USB stick or DVD.
The first stable desktop version of Ubuntu was released in 2004. It has variants developed for the internet of desktop, server, cloud, and objects. Today it is used in tens of millions of desktop-laptop computers and hundreds of millions of devices.
Who is it being developed by?
Ubuntu project, Canonical Ltd., founded by South African entrepreneur Mark Shuttleworth for this purpose, to make Linux and free software a part of the daily life of computer users company was started in 2004.
Ubuntu is currently developed by Canonical and the volunteer Ubuntu community, again under the direction of Mark Shuttleworth.
Is it paid?
No, Ubuntu is completely free to download and use for both home and business use. You can install and use Ubuntu on as many computers as you want without any license restrictions. You also do not pay any fees for published updates and upgrades.
Canonical Limited promises to keep Ubuntu always free.
Aside from the promise, codes developed within Ubuntu are licensed under a free software license called the GNU General Public License.
This license is not an obstacle or an opposition to Ubuntu being paid, but under the license, the codes are owned by everyone, like a public domain.
Canonical has only brand rights to Ubuntu. Let's face it unexpectedly that Ubuntu has become paid one day in the future, even in this case, since the source codes belong to everyone, any person, community or organization can copy and maintain it under a different name and distribute it for free, by copying the existing codes of Ubuntu.
Canonical is not from the sale of the Ubuntu operating system; It generates income from the sales of various administrative software developed for cloud and server systems from organizations that want to get professional support in the use of derivatives such as cloud, server, and desktop.
