Introduction
The feud between Rick Prime and c137 Rick is the central conflict of the Rick and Morty series. What's not obvious is why Rick Prime decided to hurt c137 Rick.
TL;DR
Once Rick Prime realized that c137 Rick couldn't be controlled, the only way he could stay "on top" was to kneecap c137 Rick as soon as possible, because that was the last moment that Rick Prime could hurt him. After that point, c137 Rick would be as powerful as him.
In other words, Rick Prime had to psychologically sabotage c137 Rick before he even had the chance to become an enemy. And if it weren't for "evil" Morty, Rick Prime would have won in the end, as the need for revenge causes c137 Rick to attack without enough preparation.
The slavery of the Citadel of Ricks
During Evil Mortys takover of the Citadel of Ricks, it becomes apparent that most Ricks aren't able to leave the Citadel because they do not know how portal travel works, nor do their own portal guns with functional portal fluid. The Citadel of Ricks shows the weakness of a monopoly: if a single person is replaced (in this case, by a Morty) the whole structure is in jeopardy if that person decides to be evil.
While all the Ricks have the capacity to be free, they instead chose the safety of the citadel.
It seems that c137 Rick is the one who knew how portal travel worked, and it seems as if his contribution to the citadel might be portal travel. Which is why no one else bothered to secure it properly against sabotage. The fact that Rick knew how to "hop" through the security mechanisms to teleport the citadel entire base into a Galactic Federation prison implies that Rick c137 was intimately familiar with the way portal travel was setup for the citadel.
Ken Thompson's "Reflections on Trusting trust" shows that in the end, the only thing you can trust is what you created: Evil Morty, Rick Prime, and Rick c137 worked out portal travel on their own; the rest of the Ricks end up in a blender.
Why IT companies discourage you from looking at the source code
It's quite simple, it's about power. Doesn't matter if it's an open source project or not, there is an underlying power hierarchy, and knowing how the software works in-depth makes you a competitor.
More practically, you are discouraged from forking a project, as this duplicates work (or so it seems). In reality, it encourages growth and diversity and makes the project less vulnerable to security issues (if done correctly) as the two forks become "genetically" different. And you end up having two competent Ricks instead of one.
It's important to note how on the Citadel of Ricks a bunch of Ricks were turned into cops, plumbers, journalists, because that's what the Citadel needed. Similar to Spirited Away, you lose a part of your name (identity) while participating in these institutions, whether corporate or open source.
