According to Wikipedia, Yugabyte (the company) has taken 290 million dollars of VC money. It's probably a safe assumption that they will follow the same path soon enough.

This won't prevent them back to paywall in future if investors ask.

True, but unlike BSL you can fork the last Apache commit the day they do.
