The one in my bathroom is from Osram and it certainly wasn't cheap, it still takes about 3 minutes to reach full intensity, which is a difference between a dimly lit and a bright white room. I also heard that they don't nearly last 10 years if you turn them off and on somewhat often, which is underlined by the one in my living room failing after less than 5 years. I'm not sure, but it's even possible that I had to replace them a few years ago already.
How often I turned it on and off shouldn't matter because on the package it says they last about 10 years, so if they break after about half that time that's pretty weird.
I didn't change anything to suit my perception of CFLs, I've got a new lamp that I use almost exclusively now, it's also got CFLs by the way.
You're also right that one laboratory doesn't prove a thing but if there is a rumour of that sort, the EU should be checking it or prove it wrong if they have already checked for such problems´ as long as they want to force us to use CFLs.
