The PinePhone could bring the Linux mobile ecosystem to life
One point that should be repeated ad infinitum for those reading about the Pinephone for the 1st time: it's all about the freedom, not performance. One doesn't buy the Pinephone to brag about its technical achievements with friends, but rather to contribute building an ecosystem, even just by spreading the word, of people who put freedom and privacy above everything.
I also should be repeated ad infinitum why its hardware is limited compared to other devices, and I don't mean the well known ones but also those built by the hundreds of thousands by Chinese factories then relabeled under a dozen different lesser known brands. The reason is that Pine64 had to make all of it from scratch since obtaining any meaningful technical information from those hardware makers is impossible, so they had literally to pick what hardware had the most open documentation available.
Supporting them is our way to send a strong message: "we've had enough of your black boxes". Big players of course won't give a flying damn since the market of privacy conscious users wouldn't represent a fraction of a fraction of their user base, but hopefully that will help convincing other manufacturers to publish their specs.
Phones aside, there are other ways to help them. I'm waiting for a beefier version of the Pinetab, am considering the PineBook pro (with EU keyboard which is out of stock) and in the meantime got their mini solder iron which works surprisingly well (and I have two Wellers).
