the fancy ones are $8,000 instead of $80 is because IP laws protect monopolies. in an open ecosystem where everything is free as in libre, any person designing medical devices could interoperate with everyone else designing medical devices. ever call to every piece of hardware would be workable by anyone who wanted to. every program even one privately funded, would then be opened to the community so their competitors could learn what you did and how and be able to build on what you did.
and if that smells like lost profit to you, maybe it is, but it's better for everyone. there is no vendor lock in forcing you to use inferior or vulnerable platforms. there is no 'upgrade cycle' that hardware vendors crave, the free market is always releasing inferior hardware to generate new upgrade cycles.
the government is supposed to be fixing things which corporations do wrong and they just don't care it seems. planned obsolescence.... do i need to rant more here?
if you think of sick people only in dollars and cents then you are in need of some morality. if you think we need to reinvent every medical tool every 20-30 years to 'fund' the proprietary developers of hardware and software then think of all the things that could have been done with those people not doing BS work, in a civilization where people are more than the dollars they have in their wallets.
