Valve is generally supportive of mods (hell, a Portal 2 mod was just released a few days ago) but it seems like recreating Team Fortress 2 was pushing it… Really sad, honestly. I really hope Valve would just strike a deal with these devs and make it official rather than throw away the insane amount of effort they put into re-building TF2.
Black Mesa is a remake of a single player game that Valve wasn’t planning on remaking any time soon, more profitable to make it official and take a cut
TF2 actively still makes them sht tons of money, no profit in splitting the fan base
