Ask HN: Is Apple repeating the same mistakes it made 25 years ago?

This is a possibly interesting question; I will try to explain how I just arrived at this conclusion in a discussion with some friends. Back in the rainbow-colored Apple area we were big fans of the architecture, alongside with Amiga and Atari. However, all three of them faded away because of one simple mistake: they had either vendor-lock-in (Atari, Amiga) or made it hard to develop for the platform because of exclusively proprietary tools and compilers that were impossible to come by legally (Apple). They vanished against DOS on the long run and we (had to) moved on (to DOS :S). Then came Linux and we happily switched our development platform, yet mostly still using Windows for multimedia and/or games (except for the "core" Linux guys, but then to them this whole question should be irrelevant, anyways). Then Jobs "came back" with the glorious ideas of a FreeBSD-based OSX and moving on to Intel processors that combined the two worlds, so we switched (again). In our discussion, we at least to some degree even agreed the true reason for the recent rise of Apple is not so much in iPad or iTunes alone, but the ability to develop open software on an Intel platform that works almost as if it were Linux while having the comforts of the "closed source" world: no longer we have to dual-boot Linux for work and Windows for multimedia (the games guys probably still are Windows, but whatever), and a platform that is dead-simple to use for non-IT guys. All was fine and up until recently there was nothing seriously wrong. But now Apple has dropped support for Java (the probably most followed language) and at the same time has created the "Mac App Store" (MAS). We have already seen the reception to the "iPhone App Store" (PAS) from the open source community - e.g. from the VLC guys, so I won't comment on that any more. And, for the MAS, you even need to pay $99 to get "into" it. I have no exact idea how open source-unfriendly the MAS is vs. the PAS, but I doubt even if it seems rosy now it will not be long before there is a real difference between the PAS and MAS. So, are the Apple guys apparently about to cut one of their "life support veins" after the other, and Android, etc. will take over the mobile sector and Linux/Windows will be again the norm in the home computing sector? I at least am seriously considering moving back to Linux again, and I am seeing patterns in Apple's current policies that make me think the question I put out to you guys has at least some substance. So, please, comment!
