If we go to the Ubuntu website, the first reference to Linux is mid-way through the page, as can be seen in this screenshot:
Here in "More than Linux", the word "Linux" is written without the registered trademark symbol ®.
This violates rule number 1 of The Linux Foundations rules on the proper use of the registered Linux® trademark:
- For each web page, advertisement, or publication, the first prominent appearance of LINUX should feature the “circle R” character adjacent to the X, as follows:
At the end of the Ubuntu web page, we can read that:
© 2021 Canonical Ltd. Ubuntu and Canonical are registered trademarks of Canonical Ltd.
There is no trademark attribution to The Linux Foundation. This violates rule number 2 of The Linux Foundation on the proper use of the Linux® registered trademark:
- At the end of your web page, advertisement, publication or media broadcast, include the following text in a legible font and size:
Linux® is the registered trademark of Linus Torvalds in the U.S. and other countries.
Why Linus Torvalds and The Linux Foundation does not sue Canonical, and other distributions that abide by the same practice?
Why they don't sue everybody here on StackExchange that uses the Linux word for the first time in their post without the ®? Or don't put the attribution at the end of their post?
If Linux should gain in the desktop market, can The Linux Foundation and Linus Torvalds one day just wake up and sue everybody?
*Linux® is the registered trademark of Linus Torvalds in the U.S. and other countries.
