There are plenty of gigantic corporations who are probably looking forward to eventually acquiring parts of Google. I wouldn't put it past Verizon, who has not only partnered with Google but also fought for telecom control against them. Don't we also need to break these companies up as well? Or do they have too much influence in the government? Ajit Pai, for example, famously worked for Verizon before government.
I'm not trying to protect Google. But I just think that the government needs to find a way to enforce these breakups more evenly or else it just leads to further consolidation, as you pointed out.
