Do we, as an industry, have such short attention span, that we forgot how Microsoft abused their monopoly in the 1990s to force everyone to use Internet Explorer? Now that Google is doing the exact same thing, nobody seems to mind.
Because the tech gigacorporations have literally spent the last three decades brainwashing us into accepting shit like that and even convincing us that it's better this way.
I remember using Netscape (my Google keyboard didn't know that word) before Firefox and SeaMonkey. I mostly used SeaMonkey to edit HTML and Firefox for my casual browsing.
