I agree why is there a OnePlus & Motorola category section in the forums but none for other devices like the Nexus line which seems to be one of the more popular devices in this community. I wouldn't want to fill up the general category with Nexus 5 specific topics.
Also a Nexus 5 user here.
I just became a patreon as well.. I trust that the funds are going to the appropriate party (Marius) and I trust that Marius is lead developer behind the ubports project. He has done some great work and is continuing to make improvements on a frequent basis. I strongly believe ubports is a great contribution to the open source community. His work is allowing me to use ubuntu touch on my nexus 5 as a daily driver, I would like to continue to use it and receive updates. This is why I am funding this project. Why does the cost breakdown matter so much, I don't care if the full costs to manage this project is $4 a month, I still want to support the project because I believe in the cause.
