So, I want a t-shirt to show off love to open source. I need some org to buy it from (so my money counts). I also want it to have a clear message to regular people.

https://www.freewear.org/ - They support several opensource projects, so there's a good chance your favorite project is also there.

Same with https://www.hellotux.com/ - but unlike others, they embroider their logos instead of just printing them - as a result, they look "official" and last longer.

The Debian thong made me laugh. Who is buying this? For themselves, their partners? I'm imagining Christmas morning when I'm trying to explain the value of this gift you've just opened.

I have a GitHub repo that lists merch for open source projects and organizations that promote open source software.

Should update the Tor mercy link from the donate page to this maybe. Seems like one needs to contribute to be able to earn a shirt 👚

- Thank you for the suggestion! I've added the link you provided alongside the donate page link :)
This comment right here is going to make somebody $50. From me.

Please don't call regular people "normies", it creates a needless boundary between those who use FOSS and those who haven't yet.

Yes, that's why I put it in quotes, because I don't like using it either but at the moment I couldn't come up with a way to name normal people that don't know about the world of open source 😅. So thank you. Will see if I can change the title.

Edit: done!

Tor has (may not be available anymore) a shirt to support abortion access and it says "privacy is a human right" and it's one of my favorite shirts

The Tor shirts look incredible! Last time I looked, you can "purchase" a shirt when donating a certain amount (either monthly or as a one-time donation).
- Oh yeah I think that's how I got it
- Damn I wish ! I just checked their website and did not see any mention of purchasing a shirt like that. They do however reward you with a shirt if you contribute to the project (fast relay, research, translation etc…)

I really like simple black&white T-shirts with just a logo.

Some will recognize it and come say hello. Most will think it's just a brand. Some will ask what it is and I will gladly explain.

This Creative Commons shirt is one of my favourites.

I rather like the FSFe for general Free software stuff, but you may find nicer-looking stuff if you visit merch store for specific projects, like GNOME, KDE, etc.

Somebody will suggest it anyway: https://based.win/

ha. That site is fun. I'm also clueless about some of it. Do you know what the "Come and find it" shirt references? I have a couple of guesses, but I really don't know.
- That looks like the Monero logo to me. So I think it is a parody of "molon labe" referencing money instead of weapons.

I think fdroid sells merch or maybe i'm misremembering also i'm kinda sure the guardian project sells merch too.

I really dig Signal‘s new long-sleeves. Depending what aspect of FOSS you like this might be something for you: https://shop.signal.org/

The problem with signal (which I love and use) is that sadly they could really f_ck up with a simple decision and sell out. That's the issue with such centralized companies.
- Sure, I agree. The problem is (and I'm sorry Matrix fans) but decentralised services don't cut it for messaging at the moment. I'm on multiple Matrix instances which I use for different groups. One more tech savvy than the other, but still. Message can not be decrypted, or toggling one wrong switch and all messages become unreadable without you knowing. I would absolutely not have been able to switch 90% of my contacts to Signal if that were the experience.
  
  Centralisation does not inherently have to be bad and Signal has been operating with good faith for many years now. I don't see them selling out anytime soon and I think they are our best shot at a good FOSS instant messaging contender for the broad masses.
- Yeah, that's a possibility. However, as some Mastodon folks said recently, no platform is forever. Signal's prospects seem reasonable to me, right now. If they co corporate and enshittify next week, I won't feel my time and investment with them was a waste, nor my financial support (which hasn't been much, tbh).

Damn!
