I am certain that nobody is considering shuttering a business unit that has an annualized revenue of $16 billion and is growing 46% per year. Anyone who is “surely debating” this would be fired from management at any sensible company.
Google isn't interested in being a minority player in any market, if they can't capture it, they will eventually leave it.
And let's be real, a huge swath of VC funded startups recklessly engage in "growth hacking" to acquire users, without a legitimate business plan, usually, e.g.
Step 1: get users Step 2: <magic happens> Step 3: Profit!
And then it turns out their ideas for monetization don't work, and they get an exit via acquisition by one of the big players as the VCs try to get some of their money back and leave someone else holding the bag.
SV is littered with companies that had millions of users but ended up folding and selling, because ultimately, running a business isn't free, and those users have to generate enough revenue to cover costs plus ROI.
Which is to say, there's probably a decent number of apps Google created and shut down, which probably would've been pretty successful companies on their own with a modest monetization model. But Google never attempted it, because the user count didn't hit nine figures.
Fortunately, AGI is almost certainly not possible in the next decade.
Of course the short-term profits being lost don't seem so short-term at this point, so Google is surely debating internally on how long they want to continue this strategy if it doesn't begin to pay off.
