Tux Guitar comes to mind but some things like chord diagrams isn’t done as well as guitar pro (imo).

For chord diagrams (like at the top of GP), there’s hundreds of websites out there which show those and its probably quicker to just use those. I’ll usually just search “C chord <instrument>”.

So why would Valve do this? It may be a response to several law firms’ attempt to file “mass arbitrations,” wherein “hundreds or thousands of consumers bringing individual arbitration claims against the same company at the same time and over the same issue,” according to ClassAction.org. It’s essentially a loophole for class action waivers and arbitration clauses, though it still won’t end up in court.

Hit em right in the pocket book.
