Yes but Heathrow has around twice as many departures per day (edit after your edit:) than Gatwick.
This is on BBC news. Heathrow is twice as busy as any other airport in the UK. It's the easiest major airport to reach from London (other than LCY which is not that "major"). I literally know people who are leaving from Heathrow this week and are affected by this. C'mon, it's newsworthy.
