Add Apache license into all font folders (This will live as a dual license with the OFL)

[mjabbink]

LICENSE-Apache.txt

[inferno986return]

So this means the entire family is officially dual-licensed with Apache? Cool, I'll update the Wikipedia page. :-)

[mjabbink]

yes, dual license.

I think many font folders are currently missing license.txt with OFL license as well.

@alisonjoseph Can you tackle this? If not let me know.
In addition to making sure all the folders include the licenses they should also probably be renamed to:

OFL_license.txt  
and  
Apache_license.txt

Github relies on the fact that there is one LICENSE or LICENSE.txt file in the main folder of the repository. This allows Github to "detect" the license. Then, an extra badge appears in the Github UI, and the repo to be found when users are looking for repos licensed under the specific license:

• https://help.github.com/articles/adding-a-license-to-a-repository/
• https://help.github.com/articles/licensing-a-repository/

Since Apache 2 is a more liberal license that can be applied to any software, not just fonts, I recommend the following:

1. Rename the current LICENSE.txt to LICENSE-OFL.txt. This will contain the OFL license that applies to the fonts.

2. Add LICENSE.txt that contains the Apache 2.0 license. This should be the “default” license for the entire repo — because this way, the scripts and other files in the repo will also have a license. The OFL license can only be applied to fonts, so right now it’s unclear under which license the “other” files are licensed under.

3. In README.md, change “Plex is an open-source project (OFL) and free to download and use.” to “Plex is an open-source project and free to download and use.”, and at the end, add the following text:

---

License

All files in this repository, including the source and final font files, are licensed under the Apache License, Version 2.0. In addition, the source and final font files are also licensed under the SIL Open Font License, Version 1.1 (OFL) with Reserved Font Name "Plex". You can select which license terms you wish to use, modify and/or further distribute the fonts under.

---

4. Create a LICENSE-README.txt file with this text:

All fonts in this directory are licensed under the Apache License, Version 2.0 (see LICENSE-APACHE.txt) and under the SIL Open Font License, Version 1.1 (OFL) (see LICENSE-OFL.txt). 

5. In each folder containing the font files, place three files:

• LICENSE-README.txt with the contents as above
• LICENSE-APACHE.txt which is the same as LICENSE.txt in the main repo folder.
• LICENSE-OFL.txt which is the same as LICENSE-OFL.txt in the main repo folder.

@twardoch I ran suggestion and copy by our legal team and they agreed so thank you. @alisonjoseph can you guys tackle this?

[alisonjoseph]

Yes I can take care of updating this.

[davelab6]

I have no objections to this, although the Apache license is unsuitable for fonts.

[alisonjoseph]

FYI I will be removing the apache license today as requested from IBM legal

[BoldMonday]

@alisonjoseph Any explanation why?

"There are issues we need to discuss if we keep want to have IBM Plex under Apache
IBM Plex hasn’t been authorized for Apache usage yet."
