What do you mean by "gave"? If that someone is making a copy of the
file, that someone will be the owner of the copy, and thus able to do
anything to it. Only users that do not own a file can be prevented
from altering it. If the file is set without write permission to the
owner, all that means is that applications run by the owner can choose
not to write to it based on the lack of permission, but this is not
enforceable.
