Compatibility through source availability (with the right to adapt) is a good strategy though. I've used Linux and explicitly chosen open source software since 2004. There's not a single program I'd like to run that does not work today. I've never been bitten by any such compatibility issue. Binary compatibility is crap though. You are likely to have issues if you try to use a package you found outside of your distribution's repositories for the specific release you use. I guess AppImage and things like this will improve this sad state of affair.
