You've really got two licenses there: The Apache License 2.0 and the MIT License.

Both have restrictions that require copyright and other notices to remain intact. As indicated here for the Apache License under Licensing conditions:


in every licensed file, any original copyright, patent, trademark, and
attribution notices in redistributed code must be preserved (excluding
notices that do not pertain to any part of the derivative works); and,
in every licensed file changed, a notification must be added stating
that changes have been made to that file.


And here for the MIT License under License terms:


The above copyright notice and this permission notice shall be
included in all copies or substantial portions of the Software.


This is the reason why you're seeing these notices above. So legally, these notices shouldn't be removed from the works/files in which they're found.

As a benefiter of other people's work, it's also ethical to give them fair credit and honor their licensing terms.
