If I’m paying for software, I should be able to keep a working version

I develop on Linux and pay for several cloud-based tools, so I’m not opposed to subscriptions. But every subscription software product should provide a documented offline mode and a downloadable, cryptographically identified last-known-good version when I cancel or the service shuts down. JetBrains’ perpetual fallback license points in this direction, though it covers a defined older version rather than the product I was using at the end.

That would be meaningful digital ownership, but not full ownership. If the copy still needs periodic authentication, proprietary formats, or a live server for essential features, I’m holding a limited license with fewer failure points—not a genuinely independent product. Security updates, third-party licenses, abuse prevention, and maintaining old builds are real constraints; a frozen release needs clear support and compatibility limits. Still, calling it “buying” software feels dishonest when a company can make it unusable overnight. Would developers trust this kind of guarantee, and what minimum rights should it include?

The minimum should include offline activation, a signed installer or container, and documented export formats. I’d accept “no future security fixes” if that is stated plainly. The important part is that cancellation or a vendor shutdown cannot reach back and disable the preserved build.

I’m wary of making “offline” sound like a security property. A frozen binary can preserve a serious vulnerability, and removing authentication can make abuse easier. But those are arguments for an explicit end-of-support warning and a safe archival release—not for pretending the customer owns nothing.

From a product angle, this is probably workable for desktop tools and much harder for services whose value is mostly hosted infrastructure. I’d trust a guarantee only if the contract names the exact version, activation method, export formats, and server-dependent features. Vague promises are just nicer cancellation copy.

Current consumer rules mostly address conformity, remedies, billing, and data portability; they do not generally create a right to keep using the software after termination. That gap matters. A last-known-good copy would be a useful contractual right, but it should not be confused with unrestricted ownership.
