Prices have become a bigger issue in the last few weeks, as the Warriors landed in the finals against the Cleveland Cavaliers. For the finals, the team sent prices through the roof.

Mr. Williams’s not-great corner tickets rose to $400 from $50. Pretty good first-level seats — which during the regular season go for under $200 — are selling for a face-value of $1,000 to $2,000. On the secondary market, the tickets are going for much more. One anonymous fan purchased a pair of courtside seats for Game 7 of the Western Conference finals for $58,000. ESPN reported that several members of the Cavaliers declined to purchase tickets for their families at Game 1 and 2 of the finals because prices were just too high.

Given the prices and the team’s connection with tech, I expected the crowd at Warriors games to resemble a venture capital firm’s cocktail party — young, vaguely geeky, demure business types, mostly white, mostly men. I also felt a sense of embarrassment for jumping on the bandwagon. A couple of years ago, I barely knew the rules of basketball, but as the team kept defying odds and breaking records, I got a bad case of Warriors fever.

Yet the crowd at the two games I attended this year, including the first finals game, was not a bunch of bandwagoners like myself. Warriors fandom is one of the few Bay Area experiences that still seems to cut across a wide swath of the population. The people who attend the games seem diverse in just about every way — by race, age, willingness to yell out and make a fool of oneself — except one: pretty much everyone wears a yellow Warriors T-shirt, and pretty much everyone looks overjoyed to be there.

Katie Jansen, the chief marketing officer of a start-up called AppLovin, which owns a suite at the arena that it shares with employees and customers, echoed that idea.

“I’ve met the owners of a suite a few suites down from us, and it’s literally a bunch of Oakland natives, a group of men who’ve been Warriors fans their whole lives, and they’ve owned this box for 30 years,” she said.

Many of the techies who now flock to Oakland told me they love this vibe. “There is a real die-hard fan base there in Oakland, and there’s something special happening in that arena right now,” said Craig Butler, Spotify’s newly hired vice president for engineering, who owns season tickets with a few of his buddies. “The energy level at Oracle right now is double what it is anywhere else — it’s just the best show in town.”
