Because software development back in the day wasn’t like how it’s now now, the charade so called software development now is a clown show: scrum, daily stand ups, open office style, tickets, tons of ci/cd BS, and of course, the wrangler aka PM and all politics involved, none of this existed like the cult it is now, I only had one experience in such environment and despite the effort I had to ask for some common sense, it was like insulting someone’s religion, “how dare you challenge the sacred methods that the silicone valley companies are using?!!”

Additionally, back in the day there was true ownership for the code you write, the code is owned by you not the company, and I know few old engineers that until now (they are retired) the companies still pay them for using their code they wrote while working there. That sense of ownership encourages you to tackle hard issues rather feeling like a machine spewing code for someone else’s business, I have seen some contracts too where the company will have ownership for anything you do while you are in the contract, including your personal projects on your own free time.
