Hi there, I'm posting here because it's more underground compared to Reddit (since I think that the dev wouldn't like it to get mainstream attention).
There is an open-source WC3 engine called Warsmash (made using LibGDX): https://github.com/Retera/WarsmashModEngine
( Discord server: https://discord.com/invite/ucjftZ7x7H )
I thought I might share it here, if anyone is interested in participating in its development. There isn't a Flatpak version yet and it also misses some features e.g.
Even then, Microsoft have a very different management approach to Activision. Although they are typically fairly hands off when it comes to purchased subsidiaries, they are probably going to draw some exceptions to behaviours that hurt MS overall, something Activision's typical management would be very guilty of.
