Basically, portraying rules (that are to your disadvantage) as some kind of laws of nature. So for instance:
"To continue, you need to install the app".
Instead of
"We're not letting you read more of this since we think you're webbrowsing this on mobile and want you to install our app"
Quite often we're indeed being lied to as if we're little children.
But in this exceptional case, the "Fun disabled by administrator", it's frank! That must be because its this third party, the "administrator", which is to blame for the restriction. Were it google themselves setting the rules of the game, they would probably not frame it in the same way.
> We've actively worked on making the website a worse experience than the app
e.g. by constantly nagging you do download the app
> No, you can't leave the table until you eat your vegetables.
> No, you can't go play until your chores are done.
It's interesting how strongly people feel about a basic little game.
(full disclosure, I work at Google but I've never had to deal with upset teachers and upset children arguing in bugs assigned to me)

The ticket is literally about distraction - the kid intends to do work, the game is literally placed in the middle and the kid forgets what was original goal. 100% normal for kids and I would not blamed neither them nor teachers.
