rasengan was a co-founder of PIA, and became involved in Freenode via "freenode becoming officially part of the PIA family" in 2017: https://freenode.net/news/pia-fn

This was later downplayed in 2019, after PIA was acquired by a company Kape with a poor track record: https://freenode.net/news/freenode-pia-changes

It appears shells.net which is another rasengan company (but not associated with Kape?) has since taken PIA's place in the organisation.
