It's a society with lots of capitalism, so of course you'll have people involved who are also involved in capitalism; you'll buy your computers from capitalist companies, etc. That doesn't seem meaningful.
So what do you mean?
I mean that projects don't need to be capitalist enterprises. For example, they can run on donations or grants, with volunteer labor, etc.
Of course there are such projects that receive enough in donations from end users to be sustained but not very many; and in the particular case of Linux desktop environments or distributions there is a lot of competition for users and donations of this type. The successful ones I can think of off the top of my head, such as Libre Office and Lichess are "killer applications" with no serious competition in FOSS.
