probably not because it's basically a Pyrrhic victory long-term. It'll drastically increase the chances of Facebook facing those issues in other countries, which would be devastating to the global business model of US software firms, and Facebook might get regulators attention again if the only significant competitor dies. I think Zuckerberg even said as much.

Oracle is more if a conglomerate these days. I would focus on cloud, ads, data tools as the main reasons to have this business line.
