From what I have read, pizza is the most popular food on the planet. It is hardly limited to tech events.
So that may be a factor. In a world full of people who are either vegan and looking down their nose at you if you aren't or only eat keto or some other niche thing and where people complain about food allergies and yadda, pizza is the least worst option that will have the most universal appeal.
