Apple is even a more unreasonable comparison. Do you build hardware and a complete software experience for the customers who buy your hardware? Well then no, you shouldn't compare yourself to Apple.
so, you are saying you are going to change the world by imitating Google? Good luck with that.
Besides the opaque sign-up scheme and a total disregard for standards (your calendar/contacts "sync" integrates with which clients?), even today your project is much less than Nextcloud...
I used 'Google' because it's really clear for everyone how this company is shaping the world (for the better or the worst).
