They can lock down the Play store completely, that's what 99% of people and the people most vulnerable to malware are using. The problem is extending that to F-Droid and other alternative services.

And what about the atrocious title auto-translations? I'm in France, my browser is set to accept EN-us and FR-fr as languages, and my Youtube is in EN. And yet it keeps auto-translating the titles of some French videos. And the translation is so awful, it mistranslates many things and translates literally some obvious puns, that I can't believe they're using Gemini for this. They must have repurposed a 5-year old version of Google Translate. It is not consistent either, the titles are translated in the home page, but not in the channel's page.
