The password manager market does not have a dominant player like Github vs Gitlab (others). Actually this would be more true if you add non commercial offerings like Keychain passwords, Google passwords and Firefox (other browsers password managers).
Lastpass didn't have a majority at anytime. And their decline is related more to thei breaches and horrible practices. They are trying to be relevant now. They offered my university free subscription for all students and faculty and still people don't even consider them. At least this is among people who consider password managers.
Also for bitwarden the controversy was about their SDK licence being proprietary but they re-licenced to open source [1]
