I would not call it a hybrid exactly. They created a for profit company (capped profit actually) that was majority owned and controlled by a non-profit company. This seems to me like an inherently unstable arrangement, since the incentives and motives of the non-profit board were not well aligned with the minority owners of the for profit company. When the value of the for profit company soared, the instability increased and the whole thing collapsed.
One trillion in debt is peanuts. The US debt is so large that the annual interest payments are one trillion. Now that is a serious amount of debt.

There have been a number of comments pointing out that Oracle distributes a clone of RHEL as an example of corporate freeloading and justification for Red Hat's actions. It is also worth pointing out that Oracle is a signficant contributor to the Linux kernel (https://lwn.net/Articles/915435/) that Red Hat is distributing and charging their customer for. I believe that most Linux kernel development is now paid for by 5 large tech companies. Will those companies continue to support Linux if Red Hat is capturing most of the profits? No idea how this is going to play out, but it will be interesting to see if these businesses can come to some sort of accomodation under the terms of the GPL.
