No. Google uninstalling things from your computer without your permission? Now that would be news.

Actually I think the answer is yes. Or at least they're disabled.

I forget the name but I had one that allowed for a custom new tab page. It had opt-out ads, but I otherwise loved it. It kept getting disabled after each fresh start of Chrome. Debated forking it but haven't yet.

It might matter that I do have my extensions sync between machines. Extension is eventually disabled on the others as well.

EDIT: "This extension violates the Chrome Web Store policy." The extension is Modern New Tab Page. The store page is gone, so no clue what policies are violated, what I need to fear, etcetera.

I can still enable it, but it will be disabled at some point.

Does it have questionable practices? Yes. There's a settings option but it's different than the settings I see by going to chrome://extensions/ as the sole option on the latter is to disable ads.

EDIT 2: To be clear, this extension was blocked late last year, and is not part of this recent batch. At that time there were questions about whether there was a list as well. There was, like this time, no notification to impacted users.

Hmm, disabling with a notice is not a bad middle-ground actually. For the worst offenders.

It's a horrible middle-ground. Google definitely dropped the ball with alerting users of a possible breach. If there's strong evidence a plugin was capturing and using credentials I need to know to change credentials.
