For example, this newer article claims “a manager said … ‘Pull request count is the new vanity metric’”, while the original article stated that “Unfortunately it's a vanity metric”. And the last thing this newer article says about “impact” is that the name “sends a strong signal about how it should be used, particularly by managers”, matching the original article’s statement that “‘Impact’ suggests to executives and managers how this metrics should be used.”
As the original article isn’t cited, this borders on plagiarism.
