Nobody goes to work at Facebook or Google thinking "wow, I'm so passionate about adverts and tracking, I want to build a world with more ads and tracking in more places". It's normal not to be passionate about your work in that sense.
However, some people find computers frustrating, stupid or boring. Such a person probably wouldn't enjoy a job working with them all the time - and it's difficult to build the skills that let you advance your career if you're averse to or bored by practising them. You need to be passionate in the sense of finding the work sufficiently non-loathsome that you can readily motivate yourself to do it.
