There was a time that I actually would have cared about this. I used to use the shopping list feature in keep all the time and I would use Google assistant to add items. When Google randomly decided to switch to adding items to Google Express instead of keep when asking Google assistant to add items to my shopping list, it was such a small thing but it made me realize that I didn't want to give control of my digital life over to Google to manipulate on a whim. Since then, I have nearly entirely degoogled my life and I can't really say I've been inconvenienced.
Same here. It was one of those relatively small changes, but the realization that I had no real control of a relatively core utility. And that it could be vastly changed (or go away entirely into the great Google graveyard), inspired me to start moving as much as I could to self-hosted stuff or at least find more trustable utilities that I had more control over.
