>Just be honest since the start that your product will eventually abandon its FOSS licence. Then people can make an informed decision.

"An informed decision" is not a black or white category, and it definitely isn't when we're talking about risk pricing for B2B services and goods, like what MinIO largely was for those who paid.

Any business with financial modelling worth their salt knows that very few things which are good and free today will stay that way tomorrow. The leadership of a firm you transact with may or may not state this in words, but there are many other ways to infer the likelihood of this covertly by paying close attention.

And, if you're not paying close attention, it's probably just not that important to your own product. What risks you consider worth tailing are a direct extension of how you view the world. The primary selling point of MinIO for many businesses was, "it's cheaper than AWS for our needs". That's probably still true for many businesses and so there's money to be made at least in the short term.
