Not to mention that companies like Google and Microsoft also offer different levels of technical support alongside their products.

For smaller companies, or companies that want to invest less in their technology stack IT department, it sounds like a better deal to have all services provided and backed by a larger computation corporation (even if that's not always actually cheaper in the long run).

For small/new companies, approx $15/head/mo for 365 (however it's branded now) is pretty hard to argue with. That gives you sharepoint/onedrive exchange & teams, and all the usual word/excel/outlook etc.

You can go quite a ways with that before you would get close to breaking even on even a single dedicated IT person. Assuming their cloud services etc. fit your business needs of course - but that's an awful lot of companies.
