To be honest, because they're arrogant. It's the same reason they don't adhere to each OS's UX/UI guidelines (including on Windows!) It's an absolute arrogance that they are "above" these platforms.
Agreed. I get high index 1.74 by Seiko Optics. They're incredible with the most durable coating I've ever found.
People who've only gotten cheap glasses/lenses don't even know how important it is. I get my frames from DITA (www.dita.com) and they've lasted me 5+ years, never bend, warp, etc. Lenses get replaced every 2 years.
Agreed with you 100% - I also hate the nonstandard window GUI interface elements (tabs in the title bar, fuck outta here!) and the really horrific preferences pane. Chrome is a dumpster fire.
Literally been in meetings at Amazon HQ in Seattle talking about "hit lists" for popular product categories - which products they were going to take into an Amazon brand first.
