Google was reportedly amortizing (by choice) long before this was in effect, so while it might “affect them”, in practice it’s likely business as usual.
It depends on the department. My salary (in a mature product) was already amortized - I suspect the same is true of all their other mature products like Search, Maps, GMail, Chrome, YouTube, etc. But I think they were deducting salaries in the more research-like areas like Gemini, Jax, Assistant, etc. So there is net still a fairly large charge related to it, even if it isn't as large as it could be.
- In a steady state where you're spending the same amount every year, the tax burden of amortized vs. unamortized accounting makes no difference. It only matters for R&D - i.e., new products.
- I read once, although I have no idea how accurate this is, that a company could classify maintenance expenses (i.e., paying SREs and some SWEs to keep the service running and fix bugs) as non-R&D and therefore be able to amortize. That's another advantage to mature services over new services.
