Probably not a bad thing if you you believe in "antifragility". The technology will improve as it should.
I would consider KHTML as a technology. Much like v8 and blink. I have no doubt the open source technology community is capable of producing great technologies with or without big tech funding. But will it be able to "productize" them and drive large scale adoption? I have my doubts but time will tell.
Lately my feeling is more and more people realize why open technology in the hand of the people is important (it is a lot about trust), but I am not too optimistic that it will break that dynamic.
Hopefully not. There shouldn't be a "dominant" browser in the "market", there should be a huge mess of choices available. If there is a "dominant" browser, corporations will cut corners and target it directly. They shouldn't be able to get away with that. Browser diversity means they cannot afford to single out users as irrelevant and unworthy of support. They should have no choice but to support them all.
