“If you can’t open it, you don’t own it.” That’s the rallying cry for the Owner’s Manifesto. There are more and more devices and gizmos in our lives that we can’t open and fix, though, at least not without consequences.

And that’s not just because they’re using some weird-ass fasteners. Many warranties self-destruct the moment you crack the case. Manufacturers refuse to sell replacement parts or disclose software repair codes. They have a vested interest in keeping you shopping — and paying wildly inflated prices — at the repair-and-upgrade company store.

So this cartoon goes out to the folks speaking up for the Right to Tinker and the Right to Repair.

In particular, a big shout-out to the good people at iFixit. Their whole raisin d’être is to turn you into a self-sufficient device-fixing electronics-upgrading whiz. They couple very-reasonably-priced tools with free tutorial videos showing you how to fix a dazzling array of gadgets and gizmos.

This isn’t a paid plug; I’m just a raving fan. Why? Well, I’m not saying one of my kids pushed a coin deep into a SIM card slot of one of our older iPhones last year, and I’m not saying they didn’t. I am saying that thanks to iFixit, disassembling the phone to get that coin out and then reassembling it held no fears for me. (Also, did I mention that it worked afterward? Important detail.) That’s a powerful freakin’ feeling in these days of walled gardens and little sealed boxes.

And my thanks to Tod Maffin, who suggested I draw something about this and caught a typo that would have ruined the cartoon. Fortunately, I was able to open it up and fix it.
