The Pixel A lineup has always been affordable. Heck, the 4a was even $349 at introduction. The currently start a little higher, but are often around 350 Euro halfway the cycle.

Although it definitely enables the market for Pixels, they definitely don’t make much (if any) money selling Pixels, due to they’re being cheap-yet-flagship devices.
It might even hurt Google for you to buy them and not capture all your data with their OS!
