In addition, I think everyone holding PoW crypto is partly responsible for it's absurd waste of energy and the associated CO2 output. If the price goes up, it only gets worse. I won't use anything PoW again.

Nano is fast and free because it is not used much. How many transactions per seconds did they achieve? I think it was in the ballpark of a 100, much too low for a global currency. Let's say 10% of the earth population want to use nano once a week. Then you need 0.1×8e9/(7×24×60×60)~1000tps. Then it might replace paypal, but not cash or card, and the microtransaction usecase is even farther away. Indeed it seems better than bitcoin, but that's a low bar by now. I do like nano's idea of voting weight delegation, it seems like an elegant solution to keep the power over the system in the hand of the user/owners.

At the moment I feel a centralized privacy coin would work best for me. Centralization brings performance and the private part avoids excluding participants.

I'm surprised to hear xmpp on mobile works for people. I tried a few times with a friend. I'm on Android, she has an iPhone. And it always was too unreliable. The worst part is that half of the time messages are not delivered or very late. But there are also problems with attachments. We tried different clients and servers.

For macronutrients and android there is waistline¹(available on fdroid and google app stores). It's pretty much what you asked for, open source and it uses OpenFoodFacts. It's more focused than myfitnesspal, but very usable and I think eating habits are too intimate to share with a company. Plus with myfitnesspal I feel like I'm working for the company when I add products to the database, not so with OpenFoodFacts.

They offer an app version on their website that does not depend on play services¹. I've been using it on a "google free" lineageos for quite a while (years?) and it works very well.

The last part depends highly on your location. In Germany there are law firms specialized in watching popular torrents. They make millions from threatening users with legal proceedings and if you leech popular content you're more likely than not to get a letter from them.

> and I have heard other newer projects exist???

Yeah, know of librepcb [1] and horizon [2]. Both try to solve kicad's library problems. Librepcb files are designed with version control in mind, which I like. Horizon used parts of kicad (like autorouter) and is more feature rich.

I probably would have switched to kicad by now, but these new projects seem nice, too, and I decided to wait and see where the community settles. Hence, in my case, variety in open source hurts adoption.

Is it really 100% open hardware? Did they release the design files yet? They did release them for older Turris products and placed them under Cern OHL [1], but last time I checked they did not do so for the Turris Omnia [2]. I was a bit disappointed about that, since they promised it to be open hardware during the crowdfunding.
