for most, i would assume it's largely just that during the time of the naïve web, there was a period where google kind of was the company, so people started using it for everything (think shortly before and then during the early google+ era). 10 years later almost every normie who didn't start using apple products uses gmail and chrome simply because they legacied into it from when they were younger and less aware of the negative aspects of the practice.
