Charging cable / cable and lock code for television. Take away?

During the Christmas holidays there were 2 days where my sister had to work. Each time late shift. Now she did not want her son playing the phone or laptop all afternoon, or watching TV. So she took along the appropriate charging cable, and provided the private television channels with a lock code.
So he could only play for a certain amount of time with a cell phone or laptop and in tv he could only see the public broadcasters (ARD, ZDF, etc.) (where nothing clever comes for him).
Since his friends' parents also look to their children not constantly on a screen (cell phone, TV, console, etc.) look, and the charging cable for his devices do not fit, it would have brought him nothing to visit friends or invite them.
I think the idea for the occasional use not so bad, even if it is clear that children are very resourceful and the son of my sister in the long term finds an alternative.
What do you say?

If it helps, why not.

Somehow I get a déjà vu in the story.

Put on annoying music and then make yourself from the dust… ^^

When my came in the teenage age (that's the age where the parents become difficult) there were no such backups. Therefore, I always have the stations that werdne werdne should be removed from the station list of the telly and then there was (thank god) a lock if you wanted to change something. At the time it was a bit harder for the mobile phone. There were no features that limited the phone. So my had a prepaid card with which you had to learn to get along with your credit. The Spiekonsole (at that time ne old of Atari) since I have always taken out the fuse in the appropriate power supply. The Pc system I could lock thanks to appropriate software (at that time already) or time limits and synonymous Web filter use.

That children are inventive is completely normal. But you will also realize that you will reach your limits once you have reached them. Therefore, a clarifying conversation is important. Information is everything.
