I assumed that they get this option for free instead of buying an app and less stuff to install generally.

If Apple's option is worse (which I doubt, at least for English) and/or original app is free then probably consumer suffers a bit. But if consumer is worse off then it is better because AFAIK American anti-monopoly system focuses on consumer's well-being so the more examples of consumer being worse off the easier to attract courts and regulators, isn't it?
