I hear what you are saying but that's not an example of a systemic degradation of corporate culture, that's an example of one company vs others. I have been working since the mid-90's and there are a lot of rules, processes and procedures that are now widely adopted by default across the industry. These rules were not always there and from conversations I had in my early years it used to be much worse in the 70s and 80s. Don't get me started on how bad it was for women, queer folk and minorities.
I like how the last commenter is both pedantic and simultaneously clueless.
