Not clearing a road means fewer people use it, but you not going out with a shovel to clear a public roads isn’t you discouraging their use nor is you canceling your plans to clear said roads.
The default situation is whatever was yesterday. I’d be astonished to learn that even a single significant civilization functioned without subsidies or patronage of priorities held by a society’s leaders.
It didn’t create a level playing field, it just discouraged a very specific type of R&D while ignoring all others. All other types of employee salaries follow certain rules and some can optionally follow R&D rules. Software is now the only one required to follow 5 year R&D amortization so the deck is now stacked against software.
