Of course it is. Phone makers could make so that you have to jump through several hoops to get to the "side loading" portion as a compromise. Instead Android is going down the Samsung and iPhone route to cripple the device into making it nearly impossible to root by a mere mortal curious person. Allowing a hard to get to side load switch fixes 99.9% of the issue and still allows for freedom. Google is actively choosing here to do the walled garden like Apple iPhone for profit
