As a matter of fact yes, if I were an OSS creator and people made millions from my work, some basic appreciation would be quite nice actually. If companies X, Y and Z make $10 million a month and this is partially enabled by my software, giving systemic donations in the orders of $10k - $20k a month would only be common sense in my mind.

(And I know I would have a "donation budget" if I was a businessman because I am not stupid and I know the work of which people outside my company facilitates my business further.)

But appreciation is not what businessmen do. 99% are cut-throats in all areas of their lives.
