The issue is the size of the 'update' and the impact it'z going to have on your computer performance.

If tomorrow Google was to include a Blockchain miner in Google chrome, you'd still say you consented to it by using their software ?

Because I'm pretty sure that this LLM is also going to be used by Google to gather data on the user and feeding it to Google, hence just like the Blockchain miner using our computer ressources (space & performance) to feed Google yearly benefits.
