Google being evil and assholes doesn't remove the fact that this person literally didn't spend a second to check what they clicked.
Digital safety starts with everyone, despite if we need laws to regulate the asshole companies trying to mess with people's lack of attention.
I like the idea of the keyboard being offline and the LLM stuff but so far I can't see a way for multi language input. I'm guessing it's too early in the alpha state for that but I will keep an eye open for it, it is a promising project. In the meantime I'll test the heliboard others were mentioning.
Who are you and how did you read my diary?
They clicked the install button of an ad, that's the whole point, what a weird specific detail to get hung up on anyway even if you were not wrong (which you are). It's not just an annoying ad, it's an ad hidden as actual results of a search with an identical install button. Google is to blame for that style to clearly try and cheat people and they deserve all the backlash and fines and more for it. But clicking a button that says install without checking what it belongs to is beyond ignoring any basic security, it's simply stupid, and that's on the user, not on google.
