Understandable, but considering I can get RPi software compatible board with 4 gigabit ethernet ports and fiber optics + expansion slot and is available whenever I want to purchase it, then in some cases it's a no-brainer. Really depends on use case. Some hardware will work, other might not, it depends. Screens will work if they go through HDMI or S-Video. Hardware should work if it uses USB. GPIO pins are a different matter.

Even if it doesn't work for majority of cases, I'd be willing to play with it and try to make it work with board I can purchase than a board that's never in stock. And to be honest I even hate Chinese sites like AliExpress but some options are better than none and some manufacturers from China are offering a lot of options.
