Being ideologically motivated is not necessarily bad (understanding ideology as a worldview associated with a set of values and priorities). FOSS as a whole is deeply ideologically motivated from its origins. The issue is that there seems to have been a change in the nature of the ideology, leading to some amount of conflict between the older and newer guard.

What change do you mean between older and newer guard?

That's not something that fits in a comment. The point is, ideology as such, is not something new in this space.

Gentoo should be able to be ideological without being stupid.
