  • “I don't think your web browser should silently install 4 GB files in the background no matter what settings you've enabled, but the post claiming it's a "no opt-in, no opt-out" default being pushed on every computer in the world with Chrome installed is not correct.”

The act of opting out of something.

For parents

"opt-out" means: The act of opting out of something.. This is a fairly neutral word with no inherent risk attached. There is no real cause for parental concern; it is descriptive vocabulary rather than something dangerous. If your child uses it, context will usually make the meaning clear. A brief, curious question about where they heard it is generally enough to know whether to follow up.

For ESL learners

"opt-out" means: The act of opting out of something.. Register: neutral, standard English, usable in most everyday contexts. A common non-native mistake is to use the word in the wrong register, or to assume one fixed meaning when it is actually polysemous; always check the surrounding register and the audience before producing it yourself. In formal writing, prefer a neutral synonym or a short descriptive phrase, and use this word only when you have heard or read it being used naturally in a comparable context.
