The license in the original Atom repository https://github.com/atom/atom/blob/master/LICENSE.md https://github.com/atom/atom/blob/master/LICENSE.md has the following copyright notice: > Copyright (c) 2011-2022 GitHub Inc. IANAL but the terms of the MIT license says: > […] > The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software. > […] And they did preserve it all. https://github.com/pulsar-edit/pulsar/blob/master/LICENSE.md https://github.com/pulsar-edit/pulsar/blob/master/LICENSE.md So IMO, they are pretty much fulfilling the requirements of the MIT license it looks like. Depends on whether the copyright notice and license is also presented somewhere (such as under the About menu) in distributed copies of the modified program as well. But I have no interest in installing Pulsar just to see if they do that or not.
