we were talking about when everything started, if IBM were to hold some copyright and kills windows from start
Had IBM taken that route, then other computer competitors would have entered with their own hardware+software combinations, rather than just relying on the software to come from one source (Microsoft).
Can you imagine a 7 time bigger apple monopoly the market? competition? would be dead 10 years ago. Sure M$'s monopoly isn'y healthy, but apple's mode is worse as far as competition is concerned.
IBM would have never been able to become that large in the personal computer market as competitors would have entered as soon as they gained in popularity.
It only becomes a monopolistic problem if one or two companies are the sole suppliers in the industry. Had the market evolved to be IBM, Apple, HP, Sony, etc, then there would have been sufficient competition to spur innovation and give consumers more options.
Where it would have been a problem is in standards and formats. However, as with other industries, common commands and procedures would have been established (just like how there are dozens of car manufacturers, but all cars have a fairly basic method of control like a steering wheel, brake, accelerator, etc).
M$ at least opened up there OSes to fit every possible hardwares, such that those hardware producers can actually compete. With apple's mode, how they gonna compete?
Microsoft forces the hardware makers to be the sole sources of innovation. Microsoft doesn't necessarily have to improve their OS if they have a functioning monopoly, which certainly isn't good for progress.
If the world was full of companies following Apple's model, there would be competition along both the hardware and software fronts.
