Ethical question

Are you people serious?!?!?!?!??!?

I am, yes.

You give people such a hard time for conversions, this is a completely fucked idea!!!!!!!
For f*ck's sake, of course this is unethical. Plus it's technically illegal.

It's only a bike, this in not Darfur, let him dress his bike up as he likes, I agree it would be dodgy (I save the term 'immoral/unethical' for more lofty concerns) if he were to attempt to pass it off as something it was not when selling - but he has not said he is doing this.

You do not own the rights to use other people's logo however you like.

Of course you can ! Just don't get caught ! :P Your avatar nicked from the BBC weather website is not going to be of interest to the BBC lawyers any more than some bike fan sticking some logos on his bike or someone nicking McDonald's logo for a piss take T-Shirt.

I don't see any of this as a big thing, certainly not an ethical question.
