I can only imagine what fossil industry and other 'big guys' are paying to have it their way.

Most commercial software is rented, not owned. Your iPhone's hardware is yours, but the iOS it runs is Apple's, and whatever runs in the baseband processor may belong to some third parties like Qualcomm.
But if you own a copy of software, you usually can patch it to your heart's content. Selling patched copies may be a different deal. (Of course, easy with open source.)

One of the largest aviation consumables companies did something simiilar. A guy just picked a central state with cheap warehouse rent, then advertised quick delivery on specialty airplane radio antennas (most planes have several sticking out), composite shrouds/covers, etc. and made a killing. He uses Fedex, but same idea of picking the friendliest state for a nation-wide business.) Those items weigh ounces, so shipping costs are on the lowest tier.
