Open source versus closed source is not something a business cares about, but it's something employees care about. The price isn't terribly relevant either, nobody is exactly pinching pennies - my business trip per diem is higher than the donation cost above!

But spend has to be justified. There needs to be a paid version with at least one functional change for a business to be able to sponsor it.

We can bullshit all day to finance about it being a "business need" for... I don't know, dark mode, or for the table to list IE6, or a breakdown by country, or something that most users won't miss. But it has to be present, so we can make the case. It can't be a donation, it can't be optional, and we need to get something out of it. That's the only way to get businesses to pay for open source.
