Philosophically, yes. Vertical integration reduces competition, reduces standardization, leaves less room for innovative newcomers, and is ultimately bad for consumers.
Economically, it's plausibly more profitable to play the bundling and siloing games.
Is it bad for consumers? Monopolies aren't always bad. Some businesses work better because of the network effect. Granted they can price gouge and do a lot of market manipulation, but if they aren't don't that I don't think it's bad for consumers. But I will agree that having that power it's more likely that they will.
