Ive tweeted @bitcoin for permission to use their bitcoin logo on a t-shirt. Waiting on a reply. If perhaps it was missed or something. Is there any other way to request permission from bitcoin.org?
Can anyone just use the logo of Bitcoin without copyright infringement? As far as I know this can already be in the Creative Commons category but if you can get that special permission then much better. Or you can also modify a little and add something to the logo to make it on your own. The whole Bitcoin community will be happy to see many people using the logo to be emblazoned on any product as this can be like a free advertising for the coin. Since Bitcoin do not have an organized and centralized marketing department with a multimillion budget, mentions and uses of the logo on different products or events can be helping a lot in promoting its name and popularization of the very idea which Bitcoin is standing for.
As far as I know anyone could use the logo as fair use because or maybe no one own bitcoin in my opinion and besides there are already a lot of bitcoins logo in the internet and a lot of people is using it as a assets so I don't think they are going to sue you if you are just a small business or a small creator maybe if you are a big company. Also, you could see a lot of bitcoin shirts on the internet and we know that they just photoshop it you could create your own version of the bitcoin logo and easily called it fair use. But salute to you if you're asking for permission that's a great start following the guidelines.
