While you are right that Libera is ran by former freenode operators, it's not 100% the same software. When you connect to freenode the server tells you it's running ircd-seven-1.1.9, while libera tells you it runs on solanum-1.0-dev. OTC says hybrid-7.2.2+oftc1.7.3.

AIUI the old freenode folks had been working on solanum for a while now, and this was the perfect time to switch to it. So it's not the same software, but it's the spiritual successor too.

Freenode was in the process of migrating to Solanum but this was one of the projects that Lee halted (and in a very underhanded way too). So it makes sense that Libra runs Solanum
