If it was a somewhat unique name, then yeah maybe. But "opencode" is probably as generic as you could make it, hard to claim to be "squatting" something so well used already... Earliest project on GitHub named "opencode" seems to date back to 2010, but I'm sure there are even earlier projects too: https://github.com/search?q=opencode&type=repositories&s=upd...

you'll be surprised the name was actually a controversy on x/twitter since opencode was originally another dev's idea who joined the charmcli team. they wanted to keep that name but dax somehow (?) ended up squatting it. the charmcli team has renamed their tool to "crush" which matches their other tools a lot better than "opencode"
