So... don't buy it? Unless you think it's the best hardware on the market at the best price point.
And what makes you so important that every hardware provider has to bend to your will? I can't run Shor's Algorithm on my Raspberry Pi, whose fault is that?
How will Apple take away your options? That's what's difficult to understand. Either the FOSS/DIY approach has merit and will continue to thrive, or it'll die because it becomes impractical, neither of those courses have anything to do with Apple trying to prevent Joe Bloggs becoming a node in a botnet.
Until the day when there aren't other options -- which isn't so difficult to understand, really.
