I’m old enough to remember when the Baby Bells were spawned. I was young so I don’t know the full impact, but it seemed to me that this was a good thing. Of course, loose regulation and regulating since then means that it took about 25 years for them to all merge back.
Breaking up these giant corporate monopolies, ones who have too much control of your life - besides Google, I mean ones like Nestle, Unilever, Mondelez, etc - would be great. Will that happen in a world where money votes? Most likely no, sadly.
