Unless you're going to spend the rest of your life in a cave somewhere (an increasingly good-looking option), then it's a legitimate matter of perspective imo. Every activity carries some inherent risk, and my current viewpoint is that domestic entities are the worse option compared to foreign ones. Will China/Russia try to use US data to influence US elections? Of course. But you know what? So do US-based political operatives. So does Meta and Microsoft. The difference is that Meta and Microsoft have unfiltered access to our data (we give it to them), and the direct ability to lobby/bribe our politicians. Might a Chinese company try to sway my opinion on some Chinese/other foreign topic? Yes, of course. But so does every big tech company, every cable news operator, and so many millions of US-run websites. The domestic operatives have more access and are capable of doing more damage.

Yeah but this is socialized risk (political influence) for personal gain (access to the apps)

A vast majority of the public do not see themselves as vulnerable to propaganda targeted at themselves, or at least they dont see it happen in real time. So the risk is abstract to them at best but more likely seen as non-existent, while the gain is immediate and concrete.
