As is indefinitely means nothing when clients need updates. Now if you promised to open source the whole thing when turning off the lights, along with the build tools, etc. That would be meaningful. This is what I do for clients of my software and SaaS products. I give them the source code, build notes, and all related documentation. The only caveat is they cannot resell or use that software in any manner beyond their own implementation as long as my company is operational. This is how I sell all my projects. The funny thing is, when every single one of them needs a fix 1-5 years later, they've lost everything I've given them. Fortunately, I archive everything for this reason. This is like the "Lifetime Warranty" nonsense IMO. Just use your tools now, make sure you can export as necessary and if your core competency is using someone else's tools, make sure you're staying on top of those tools (and opportunities for your own company).
