@moot said this more succinctly in discord but damn if there isn't a supreme contrast between
"someone had to slip me the GoG installer for UT2004 for game night 'cause epic doesn't sell it anymore" yesterday,
and "huge free update for the original goldsrc half-life featuring major fixes for a lot of code rot, the official inclusion of content like Uplink and other addon packs that were only ever available on CDs shipped with graphics cards, in addition to making the game free to obtain for a week(end)" today.
i had to Obtain™ unreal tournament because epic turned off the master servers (which the game doesn't even need) and used that to pull all the UT games from sale, and here's valve with a major patch to the original half-life being given out for free. two different ways to treat flagship franchises i guess.
