Create an independent data center industry, ban them from selling SaaS like products, ban them from developing frontier Ai. That's the idea I've heard floated. Treat data centers more like a utility with more stringent regulations.
"At the end of 1999, 3Com began the process of spinning off its wholly-owned subsidiary Palm, Inc., and on March 2, 2000 about 23 million Palm shares (about 5% of the company) were offered to the public in an initial public offering (IPO). By the end of the first day of trading, Palm’s closing share price was about $95, giving it a market value of $54 billion, while 3Com’s closing price was about $81, making its market value $28 billion. But 3Com still owned 532 million Palm shares valued at $50 billion, implying that the value of 3Com’s non-Palm assets ( its “stub” value) was a staggering -$22 billion!!! The record shows that 3Com had no debt, more than $1 billion in cash, and a positive market value before acquiring Palm. Furthermore, 3Com had a $5 billion capitalization the day after Palm’s spinoff was completed later that year. Obviously, the financial market recognized the considerable residual value in 3Com. How then can 3Com’s stub value be negative on March 2?"

In general, spin offs create value. And later consolidations also create value. Rinse and repeat (and collect fees along the way).
