Google might have pretended to stood for something, but they have been an evil corporation since they have been a corporation. That's what corporations do by design. One relevant example is that they've been doing the "only for ie5+" with their services for 10+ years now. They killed most of their browser competition not by having a good product, but by having or buying up good services that they used to force chrome…
That’s not how I remembered it. Chrome really was a good browser and I would argue is still a good browser (for now). IE got displaced by Firefox’s predecessors because MS got caught napping - they disbanded the IE team thinking they have won. Firefox simply got outcompeted by Chrome as Google went crazy making it faster and faster. Firefox fell behind often enough that Chrome managed to take almost all of its market…
Then chrome came along and people reluctantly switched at first, then enthusiastically. Firefox had the reputation of eating RAM like candy.
