Project License not fulfilled

[OutdatedGuy]

This project is licensed under the GPL-3.0 license.

However, as the license states to provide copyright notices at the top of all source code, there isn't any included in any of the files.
It also states to add changes to the licensed work made by the contributors.

Wouldn't it be better to use MIT license or BSD 3-Clause "New" or "Revised" license instead?
