CloudFlare is not a good company, but I don't see how its nationality is relevant.
Undersea cables are cut all the time, often by accident or from environmental threats. Mitigating that is difficult.
A non-US company would be just as vulnerable to cable cuts, as this isn't the fault of CloudFlare* or the US government.

Moreover, there are only a finite number of companies and nation states with the resources to lay and maintain undersea cables.
Ideally, that would be done by some non-profit international body with buy in from many different countries including the US, but that isn't the case today, and anyway discussing those complicated policy questions is beyond the scope of this post & beyond my expertise.

In any case, it is impractical or impossible for every non-landlocked country to have its own domestic company responsible for undersea cables. Therefore, most countries will have to rely on someone else.
Moreover, those fully domestic companies would still need the cooperation of other nation states in order to connect their cables to and through other states' territorial waters.

More broadly, a fully domestic CloudFlare would still be vulnerable to the many non-cable problems with CF, like privacy. There are non-US CloudFlare-like companies, and they have their own problems. Even in terms of centralization, having an entire country dependent on one company for critical infrastructure is a bad idea, regardless of if that company is domestic.

Finally, it is impractical to make domestic alternatives for all tech. Home users, companies, and governments rely on many different pieces of software, hardware, and infrastructure (like CF). Replicating that domestically in every country would be difficult and expensive.

* Many cable cuts are outside the control of the owner; we don't have enough information to determine if CloudFlare or the US acted negligently in this specific case.
