Greetings Admins and thank you for your generous sharing with the community.
I second Sharma’s findings. On Elementor’s website, under Terms of Service, they state
4.1 Source Code License
The source code of the Software is licensed under the GNU GPL-3 terms with the following additional terms per GNU GPL-3 Section 7:
“The origin of the Program must not be misrepresented; you must not claim that you wrote the original Program. Altered source versions must be plainly marked as such, and must not be misrepresented as being the original Program.”
Hope you re-include Elementor Premium in your repository soon. :)
