Those who can afford to do so, will get the upgrades legitimately. Those who cannot will get the bootleg parts and software, just like we have done for decades in the PC space. I had plenty of functionality with a shoestring budget back in the day, and I imagine getting your 'droid hacked by the kid next door to run a variety of behaviors, will be a thing.

With the advent of open-access, AI-assisted programming, you will likely have access to a fully customizable suite of behaviors and skills with very little cost. I imagine that more regulation will be pushed by android manufacturers to control what software goes into what hardware. For safety, of course.
