There's a lot more than just free apps to consider in this scenario.

Paid apps will have to be re-purchased, your Airpods won't work as well, your Apple Watch won't work at all with Android, you won't be able to message your contacts who use iMessage without SMS, etc.

iPhone owners tend to buy into the Apple ecosystem which ends up being a whole bunch of vendor lock in, and it becomes unreasonable to switch platforms. The ability to switch to Android certainly doesn't give Apple a free pass here.
