Centralized ( #Corpocentric ) networks have centralized costs, so there will always be pressure on the central organization that controls the network to bring in more money. More users; more equipment & network bandwidth; more advertising revenue, more employees; more (higher) salaries; more (higher) dividends to stockholders; ... oops, we need more users to justify all this spending.

There are definitely costs to #DecentraLife, and I don't think we talk about that enough, but from my perspective, even spread over the whole #Fediverse, the cost/benefit ratio is still superior to the corpocentric networks.
