If avoiding sale-of-ownership to a capitalistic entity is a strategic goal, incorporating as a non-profit is one tactic. Among other protections, ownership of non-profits in the US (501c3) cannot be purchased by for-profit entities.

A 501c3 can be a parent company for a for-profit company (e.g. Mozilla-Co is owned by the Mozilla-Foundation), so it's still possible to operate a "normal" company within the IP-ownership structure of a a 501c3.

Edit: it's worth noting that family-owned businesses with a trust component have also done really well in the last 100 years. (see the NYT, which is governed by the Sulzberger family [126 years], and many others on this list: https://en.wikipedia.org/wiki/List_of_the_largest_family_bus...)
