The word "hate" here seems to be trying to imply anyone who criticises Lumo is talking from feelings rather than facts.
As you say the rail share of London - Edinburgh is higher than it has ever been, but somehow before Covid the InterCity East Coast operation regularly made profits, whereas today it makes losses. Its interesting to draw the trend lines forward, where you will discover that this missing ICEC profit is a very similar number to First Group OAO profits...

And thats before we get to the fact that Lumo especially, often because of their own choice of rolling stock, often give up on running a service in disruption and expect LNER to transport their passengers. Network Rail even allow for OAO trains to run through disruption which restricts train capacity; as a result you find LNER cancelling 9 and 10 coach trains so that Lumo's 5 cars can run. Where is the systemwide logic in that?
