If you are a good CFO, you say:
"Hey remember how we want 5 years of cash, well i just looked at selling bonds and getting cash now is expensive." For tech companies the biggest expense is salaries, so saving cash means firing people.
For the smaller companies they aren't getting investments as easily or at all. They will also need to save cash.
The next few years are going to be different.
