As others already commented a lot of content creators are getting copyright claims for just 5 seconds humming of a song and this allows them to edit that part and change it.
It’s funny how people want to edit their tweets when they misstype something but don’t want others to do so. In a video of 10min there are a lot of mistakes to be made and things that can be changed.
I moved to the UK but I still know many friends from Spain that work from 9am-1pm -> lunch break -> 3pm-7pm. Which means that in reality they can end up leaving the office at 7:30pm.
By the other hand I worked for the Catalan TV for many years and they had very flexible hours and I could leave by 5pm, but it's not that usual in my experience (and that was 12 years ago).
