I will guarantee you that there is far, far more to this story.
Clickbait outlets love (often selectively-reported) Ryanair stories because they will get 1000 replies from people saying "Disgusting airline, I never fly with them, they've let me down the last 20 times including last week" or similar. It's kind of like how any story on fast food and obesity always shows the outside of McDonald's and no other chain.
"Murray said she also asked for CCTV footage of the incident, but was allegedly told that the airline could not release the video" — I would be surprised if Ryanair has CCTV that records and monitors every passenger seat, not least because it would be used to bash them further. Maybe the reply was "Sorry, we cannot release the video as it does not exist".
The other day I was on Ryanair and I pre-ordered a G&T (this is brilliant - you can order from your seat before takeoff, or even in the tunnel waiting to get on the plane, and they bring you the drink before they start pushing the trolley along the aisle). It was brought to my seat and they said "We'll be back for the payment in a few minutes", but no attempt was made to stop me opening the little bottle before I'd paid.
When they came back I tried my Wise card, but a lot of the fintech cards don't seem to work in the sky (probably because they rely on instant verification of the balance). I had another card, which worked, but if I hadn't I doubt very much that my ⅔ finished G&T would have been snatched from me. I would have said "Oh, I'm terribly sorry, how can I sort this out?" and I'm quite sure that the crew would have come up with a solution. (The Wise card would probably have worked once we had landed.)
The problem is that some people have no respect for the professionalism of the cabin crew and imagine they can treat them like 19yo bar staff. I've flown over 100 times with Ryanair since about 2007 and while their cabin staff used to be a bit uneven, these days the service is always spot-on.
