Well...you WOULD be right, except they did more than release a bad HD remaster. They retroactively destroyed the ORIGINAL Warcraft 3. They removed graphics options that the original game had, and are holding those behind a paywall. You effectively have to pay AGAIN to get back JUST what you had before this crap released.
If you own the original CD's and can install from that, there are ways around this. You can go to one of the many mirrors out there that host old patches, and get the latest patch that does not have any of this garbage, and use that. But even so, you cannot ever click the battle.net button as it will "update". You get single player and LAN ONLY, multiplayer has been disabled except for the "new" downgraded client. If you bought it digitally from battle.net you are screwed as you cannot access the original game without pirating it. This is FAR FAR worse than anything Bethesda did. Yes, Fallout 76 is a disaster. But it doesn't uninstall Fallout 4. Imagine if it did, and that is the level of shitshow this is. It's illegal in a lot of places, and I hope that countries like Australia that have consumer protection laws nail them to the wall. Valve had to pay millions of dollars in fines for refusing refunds in Australia, and Blizzard is now doing the same thing (they have even told people that "we don't have to obey your laws because we're in the US" - yeah good luck with that).
I personally have the original CD's...I'm going to hang onto them, they could be worth something eventually (as I uninstalled all Blizzard products from every device I own back in Nov 2018). I'm just enjoying the firestorm. Blizzard is a shit company now, and I enjoy it every time something happens to harm the company. I am having a pizza party when Activision shuts them down. Which they will do when their name gets toxic enough, just like EA did to Visceral. And it's getting to that point. Blizzard is now known for low effort shovelware, and releasing half baked products for full price.
