open source
Libre software. 'Open source' is a deliberately ambiguous phrase, engineered to derail libre software.
they are for-profit, so what? They have a foundation that managers /e/OS itself so AFAICT Murena is to sell phones with installed /e/OS so you can skip that entirely and not give them 1 cent. Even funding like NLNet (which IMHO is some of the best as the project gets to decide on milestones, they are just funding FOSS) encourage projects to have sustainable source of income, what's your solution there? That they get bought by Google? Do you personally have the kind of money to make them sustainable for years if not decade?
Selling libre software is good. Stay on target.
