[BUG] Apache License incorrectly modified

[shinnar]

Describe the bug
The LICENSE file was modified by d93e9bd, which replaced all instances of "do not" with "don't". This was probably not intended; the Apache license should probably be preserved in its original form. Changing this makes the license subtly different in likely intended ways.

Expected behavior
The LICENSE file is identical to the standard one (e.g. https://www.apache.org/licenses/LICENSE-2.0)
