Please stop trolling. Microsoft did a ton of shady things. For instance: Colluding with SCO to spread Linux IP FUD [1]; suing Lindows around the world, even“ex parte,” and getting a ruling from some a Dutch judge that
every day someone could download Lindows from the Netherlands, Lindows owed MSFT an additional 100,000€ for trademark violation [2]; the whole Java Embrace, Extend, Extinguish thing; forcing OEMs to not ship PCs with Linux installed if they wanted standard OEM discounts on Windows; the whole federally-convicted-of-antitrust bit; etc.
And I for one LOVE the walled garden as it provides me with demonstrably higher-quality, malware-free apps that don’t just rip off someone else’s IP/icon haphazardly the way most Android apps seem to do. The walled garden does NOT prevent end users from installing web apps to the home screen, sans Apple approval. It is also NOT anticompetitive, unless you know something no one else does.
