If I install Chrome, I expect it to take a few hundred MBs and then only take up additional space in a controlled and transparent manner - for its cache, for example. For me, secretly adding 4GB after installation is a bit too much.
If you're okay with 4GB being added, where would you draw a line? What if it downloaded a 40GB file? 400GB?
Personally I draw the line where Chrome becomes worse than alternatives, and then I switch.
Lately Firefox has been getting better, but I still prefer Chrome for almost all my needs, so I stick to it. This barely even makes a difference to me. If it was 400GB however it would make a difference to me, and I would make more of an effort to switch to something else.
I fail to see scenario where Chrome is better than almost any Chromium alternative with exemption of Google account sync.
Then you don't have to use it.
I was just curious why would anyone use Chrome over other superior Chromium alternatives (Vivaldi, Brave, etc.) other than Google account syncing (which I can understand can be pretty big deal for many).
