Ask HN: Open-source commitment for commercial software?
33 by davidbanham | 16 comments on Hacker News.
Hi HN, I write a bunch of open source software. I also make and sell closed source products. I'm a small shop and sometimes my clients worry about platform risk should I just decide it's no longer worth bothering to support the product I'm trying to sell them. What I'd like to be able to do is put a clause in my standard EULA that says "If I ever stop offering this software on the market, I promise I'll give you the source under a BSD licence." Is anyone aware of prior art in this space? I'd love to learn from history before trying it myself.
