Don't nationalise them, break them up. A state monopoly is preferable to a private monopoly, but in this case there's no reason we have to have a monopoly. Facebook and Google do too many things.
Google? Definitely. Meta? Not really. All Meta has is two social networks and one messaging service. They haven't really experienced huge success in anything else. They MAY hit big in VR/AR space, but that's yet to be determined.

And a payment service, an ad platform, a marketplace, a VR R&D company, I never used them but I guess they also have a line of business services centred on social network communication, I’m probably forgetting plenty of things.
Additionally, Facebook primarily does acquisitions as a form of hiring, according to Mark Zuckerberg himself. They buy the company so they can get the employees to come and work at Facebook.
Oculus VR, Giphy, Mapillary and more are also successful in their space.
Just like Google's successes, the "successes" are actually built by others (almost all you list were acquisitions), but the difference (as mentioned before) is that Google sometimes acquire products for the product itself, while Facebook generally doesn't.
They still would definitely met the standard of a monopsony if not a monopoly. Its scary that an enormous number of people start and stop the information searching at google or those two social networks. I think its an oversimplification to say that just breaking them will solve the issue but they definitely handle a governmental level of power in terms of social after effects, which is why nation states target them for fake news.
On one hand you say they are so important they need to be nationalized and on the other you dismiss them as almost a couple of trivial apps. Which one is it?
Just social networking services? Modern social interactions revolve around them. Social networks are incredibly important and should be treated as such.
Communications platforms naturally become a monopoly. The biggest platform is the most useful one because you can talk to most people on it, so people prefer to join the biggest platform and it gets bigger.
That is easily fixed with legislation. We now have multiple phone companies that all interoperate. No reason we can't require the same from our many facebooks.
