The tragedy isn't in what you've said, but rather what you haven't said. The implication is already that a product of GDocs/GSheets quality should be free, as part of a large company's moat, rather than a paid for product that people will pay for.
The tragic reality is thanks to these large companies turning what would otherwise be successful standalone businesses, into free additional features.
I've used that word because Steve Jobs famously described Dropbox as a feature. Google has effectively made MS Office a feature. Apple effectively made operating systems a feature, by giving away macOS and iOS for free with their hardware sales.
Increasingly, everything becomes a feature, in search of what? For big tech, it's to sell users attention.
Meanwhile, on the other side, big media is charging us to give them our attention...
Hosting as in having some code deployed to some machines is indeed cheap. Keeping a large app like g.docs up and running, especially without breaking the bank, is a bit more tricky.
Of course, that applies to literally every piece of production software ever, but keeping a webpapp running really isn't that hard, it's honestly the bare minimum of competent software development, if you have a team of SREs up at 3am triaging the site every night you're doing something wrong. Now of course, when you get to google scale, you will encounter unique problems, but if you're at google scale your business has more than enough revenue to pay for the costs.
Also, how would you be generating revenue from these users? Just do what google does and run ads on the side? Then what's the difference?
Spinning up containers is like the bare minimum I'd expect from an ops engineer, I wouldn't call it "trivial" but it's the job.
> Also, how would you be generating revenue from these users?
That's a business question, not an engineering one, if the businesses doesn't have a plan for revenue then hosting costs are irrelevant.
Or you have to either have aspirations of becoming a big platform company or a plan to survive and be happy watching big companies push you to fifth place in a category you once dominated.
What you'd need to host/deliver something like Docs/Sheets is: a product team (2 QE, 8 SWEng, 3 SRE, 1 product owner), the product, some cloud infrastructure, and the capital to pay for it. You could go larger than that to build it, but that is plenty of people to run/maintain/support it. Assuming "large scale" is between 1M and 100M users, figure between $750K and $3M for infra. Combine that with median salaries for employees, and you're lookin' at between $1.75M and $4M (before taxes/business fees).
If you use the cheapest infrastructure and labor, you could do it for $500K. (it is mind-blowing how cheap offshore labor is. Google engineers get paid almost 8 times what some of our contractors get paid, for about the same work)
VCs throw that much cash around for a weekend trip to French vineyards. If you can actually get paying customers, even better.
That's the same thing as saying that macOS Monterey isn't Apple's invention, they just copied Xerox.
There's years of development on what Google bought and what Docs suite is now and any engineer that had developed a product for years shouldn't say silly stuff like your sentence.
