(Not the original commenter, and I can only speak from my perspective, having started working in Bay Area tech in the pre-Netscape 90s.)
I don't know that it has become more corrupt than it was ca. 1998-99, but I would say that the sleaze is shocking to people I tell stories to in other industries. Sleazy people are everywhere, but fast money and the apparent lack of a functioning institutional memory makes for easy marks.
I don't know if it is as bad as finance, as I've never worked in finance. I would guess not quite, for two reasons: (1) not as much money, even though the amounts have certainly grown, and (2) the environment changes more in startupland, which upsets some classes of comfy arrangements. But that's intuition-driven guesswork, with some residual loathing for ibankers for seasoning.
