> charging people to use toilets on-board

AFAIK this has never happened.

This is a PR stunt that is regularly used (like the idea of standing-room-only tickets) to generate a new round of press for the company and highlight how cost-efficient and ruthless they are, which aligns with their branding and keeps the story alive.

I understand the sentiment but as sibling comment points out, you're very light in the way of stating facts to back up these claims.
