That's not the issue, the issue is huge disproportion of influence that these platforms create for their owners. You are practically saying that monopolies are fine as long as you're not getting robbed. The fact is, you probably are getting robbed, by paying too much money for the dominant service.
OP seems to be resentful especially toward the mega fortunes amassed by some folks.
Regarding digital monopolies like facebook and google, those markets didn't even existed 20 years ago. It's them who created them, almost from zero. They created the need in the market. I still can't see any reason why a third party (aka government, in the name of the people) would use force to break them apart. Mostly because they're not monopolies for services related to basic human needs.
