I think Twitter has generally done that based on where you are logging in from/your account is registered to comply with local laws, all tech companies who work in multiple countries tend to do the same as if you don't at least make the gesture to comply with local laws you tend to find you end up not being allowed to do business in those countries.I wouldn't be surprised if they censored content depending on where the user logs in from
I know of people who have their country set to Germany because apparently that massively reduces the amount of nazi/neonazi accounts and bots that appear in your timeline/can interact with you due to the German laws on nazi's.
