Bad for consumers, how? Financially? How does that translate to the current situation? The average "consumer" here is paying $0.00 for Google, Chrome, Gmail, Maps, Flights, Docs, Sheets, Chat, Meet, Books, Scholar, Shopping, YouTube, News, Groups, Voice... how are you going to argue that this "monopoly" (?) is bad for consumers? Do you imagine Microsoft or Apple would've created better search, email, news, etc., or that the mom & pop shop down the store would've done that?
I can think of so many other arguments you could use to suggest the current situation is bad, but monopolies are bad for consumers seems like a really tough argument to apply here.
Edit: You need to argue more than "the current situation is bad". Because that in itself does not imply "removing the 'monopoly' would necessarily lead to the better outcome in my imagination." Exhibit A is all the behemoths trying to compete against Google and still offering objectively worse products.
