Another Brexit benefit. International entry points with the EU are expensive to run as a 3rd country. Where as before it was just another stopping point, now it is a border control point.

Modern petitions seem pointless at the best of times, but petitioning a private company seems particularly futile. They have zero obligation to even recognise the petition, let alone act on it.

I wouldn't be surprised if it doesn't reopen. Channel crossing passengers are down 30% since 2019. They've also canned the Disneyland Express.
