License change: MIT → LGPL v3 starting with v2.2.0

[SMEWebify]

Hi everyone,

Starting with v2.2.0, WEM will be distributed under the GNU LGPL v3 or later instead of the MIT License.

Why

WEM started in 2021 under the MIT License, the most permissive one there is. It helped the project grow, but it also allows anyone to take the code, improve it and redistribute it as closed software without the community ever benefiting.

The LGPL v3 fixes that while keeping the project free:

• WEM stays free of charge and open source, including for commercial use.
• Using it inside your company or for your customers creates no obligation, even if you modify it.
• If you redistribute a modified version of the core, you must provide the source of your changes to the people you give it to.
• Separate extensions can use any license you like, including a proprietary one.

This is the same choice Odoo made for its Community edition.

What changes for you

• You use WEM as is, or adapted for your own company: nothing changes.
• You stay on v2.1.0 or earlier: those releases remain under the MIT License, forever.
• You redistribute a modified version to other companies: share your changes with them under the LGPL. Contributing them back here is not required, but it is the easiest way to avoid maintaining them yourself.

Trademarks

The repository now includes a TRADEMARKS.md file: the code license does not cover the Nest2Prod name and logos.

Contributors
