That doesn't seem very "clear" to me. The article you linked mentioned those were made to go into defrost mode (and it didn't mention any brand). Meanwhile the affected Samsung devices are located in Korea and Samsung admitted it was due to their firmware update.

Also I don't see how it's unfair to expect refrigerators that cost a grand to do their one job without firmware.

Stay frosty, sheep. Or otherwise woolen mammal.

Thank-you that link - it is very interesting. The cause I wonder about is another A.I. agent attack.
