IE wasn't mainly a problem because it didn't support things, rather because it was - in the beginning - superior, but also had all sorts of non standard behaviour that Microsoft pushed and that made competition crazy hard.
Oh, and also because they pushed it relentlessly in all ways including - as was later confirmed in court - illegal ways.
Exactly like Chrome today except the multi billion fine and forced changes to Chrome is still only barely visible in the horizon.
But we will keep pushing, won't we? For the record: I think I have contacted local authorities twice officialy over the last 18 months and maybe once over twitter. If two more people do the same here in Norway that is starting to make a difference.
Same if ten people in France or Germany do it. Or if someone makes a story that goes viral or reaches the headlines somehow.
Don't give up everyone! Chrome is an excellent browser but don't think for a moment that Google won't close it down the very moment it has finally crushed competition.
