Its not 'going open source' as they were always open source, its change of license.
Plenty of other products started slipping downhill after management saw a need to change the license. Why else would you change your license terms if its not to then be able to change your business practises down the road?
I was posing a hypothetical for people that seem to think they were never open source. They packaged a proprietary part of Bitwarden into the app and quickly relicensed it to GPL.
I don't see how you think introducing a GPL license is gonna lead to worse business practices? Unless you don't know what the license is.
Choosing GPL over AGPL for this kind of project combined with the previous recent CTO messaging is very telling if you consider the architecture of the software(s).
