One thing about debugging is that there isn't much lock-in. If you don't like the debugger or it goes away, switching to another debugging approach is very easy. Your workflow doesn't have a hard dependency on it (other than to the extent you enjoy using it).

It's a bit like Github, which also isn't free software, but so many free software projects use it, in part because people think they could easily switch away from it if they wanted to. (I think in practice switching away from Github would far harder than switching debuggers.)
