IANL but I've taken it to mean that releases acquired under the original license would continue to be governed by those terms.
I'm liking this new approach better than e.g. perpetual AGPL though, as it provides incentives for businesses to acquire commercial rights while avoiding any dead end agreements that outlive the startup entity.
BSL is an _eventual_ open source license. 4 years after every version release, that code now transitions to being MIT licensed. SDV's roots are in academic science (MIT), so we wanted to make sure researchers could still use the toolkit for their work.

Tree of Heaven is worse still. I tried to clear a small property of it for a couple of seasons, and failed, so I unconsciously take note whenever I see it growing: it's seemingly everywhere.
Never dealt with those, but the worst for me was Brazilian peppertree. I had just one in my backyard and the best I could do over a decade was managing to keep it from spreading.
The most effective method was to hack into the bark to apply an herbicide, and give it a couple of weeks to make its way into the roots. Dig out as much as you can once the leaves all die. Good luck!
Neither was a startup though.
