I Love NY More Than Ever

Is it acceptable to change a logo according to a cretin event , occasion ,and sometimes even disasters ?

changing an existing logo by adding stuff and changing a bit of it for example :" i love NY "

to
" I LOVE NY MORE THAN EVER " after 9/11

in this example "the" same designer who designed i love NY designed i love NY more than ever,
he changed his own logo .
In my opinion this is acceptable and even contains a strong msg and associated with a cretin disaster which is the booming of 9/11
here he made a cause for this new logo -plus a msg- and awareness.

it depends changing an existing logo by "THE" designer or by "A" designer

for example Jeddah logo
to

after what happened in jeddah the Floods
the new logo means Jeddah sank
in my opinion no one have the rights to change an existing logo only the designer who designed the logo it self can change it .

all though Jeddah new logo reached the public in a cretin level, that means it was successful somehow ( still everything has some exceptions )
but this simple change affected people seeing the logo , ex: the Jeddah logo is now in the eyes of whom they saw the new logo is associated with the floods of Jeddah no matter what, so that has affected the people
in conclusion my opinion is that only the designer can change his own existing logo .
because changing this existing logo by "A" designer which means any designer may reduce the value of his work and would not be respected .
so only the designer who designed the logo it self can change it . At least that can be fare and square .
