I have a hard time imagining software companies benefitting from copyright extension. The vast majority of software is obsolete literally decades before copyright expires, in most cases the source code will be lost or otherwise unavailable even if the copyright expires, and the CPUs able to run the software will no longer be manufactured. A movie or song might become a classic, but software just gets old.
