If they are big in the sense of having a lot of employees then this is good news. If they are heavily capitalized low employee count businesses like a lot of tech startups, then that’s a bad thing.
Unfortunately I agree here. We're not out to save as many small businesses as possible, but jobs. If we want so save small businesses, we need to earmark more money for small businesses only; especially should this extend beyond April.
Pure profit maximizing behavior is devoid of morals or conscious reflection, so this behavior isn't surprising. If the govt didn't want this to happen they wouldn't have allowed it to, it's not like they didn't see this coming.
edit: I'd argue that this isn't devoid of morality since it's literally a zero sum game, and the negative externalities are pretty clear. Making money at someone else's expense is definitely a moral quandary.
