I believe we can rightfully criticize the anonymous masses behind social media for the mass hysteria surrounding HRH The Princess of Wales surgery and recovery (which KP have been very forthcoming about) and making more out of an edited picture than necessary without infantilizing TRH The Wales or dismissing legitimate news agencies as clout chasers or reputational hitmen for the couple.
TRH The Wales have been very calculated with regards to how they and their family are seen in the media. They have agreements where they provide access to them/their family in certain instances (ones that highlight areas that are important to them/Great Britain and show them in their best light), while keeping the press away from their private lives. They have stayed silent when any amount of rumors have come up about them, and it's work so far. It's unfortunately for them that the moment they need that privacy the most, the reason is so big that the public's demand for information is greater than usual. They rightfully won't be bullied into giving more private information, but they try to appease the public as much as they're willing to. It just ended up backfiring, a rare misstep for the couple.
News organizations like AP and Reuters aren't tabloids or propaganda agencies. These are legitimate news organizations whose bread and butter are serious news stories like wars, regime changes, history-making moments, etc... They certainly do not need to humiliate TRH The Wales for clout. And although I didn't mind the editing of the picture, those organizations should; even though there's no evidence that HRH The Wales edited their photo for the sake of misleading anyone, others might heavily edit their photos to mislead, and AP and Reuters and Getty and others' accuracy depends on making sure that doesn't happen. On the other side, if they rejected pictures similarly edited based on their standards, then it would be hypocritical to accept TRH The Wales's family photo even if there was no assumption of misleading within it (which none of these new organizations have implied).
Overall, it's a beautiful picture that's been edited to show the subjects in the best light and illustrate that HRH The Princess of Wales is doing well. AP and Reuters and others probably respect the sentiment, but the picture is too edited for their standards to publish. Nothing more, nothing less.
