Although this is based on "leaked" info that's how it works basically now, you don't get online multiplayer by subscribing to "Game Pass Console" you need to buy online play (Xbox Live) separately or just go for "Game Pass Ultimate" which bundles everything they offer. It just does not make sense. Currently, this is all the tiers or packages you can subscribe to:

Xbox Live Gold: Multiplayer, Games with Gold
Xbox Game Pass Console: Full Game Pass catalogue on Xbox Consoles, NO online multiplayer for Xbox consoles, NO EA Play for Console
Xbox Game Pass PC: Full Game Pass catalogue on PC, EA Play included for PC
Xbox Game Pass Ultimate: Full Game Pass catalogue for Xbox and PC, EA Play for Xbox and PC, Online Multiplayer for Xbox, Games with Gold for Xbox, Cloud Gaming

Since in their now official announcement on youtube that they are basically rebranding Gold to Game Pass Core and removing Games with gold while adding the 25 game pass games instead it just feels daft that they don't add online play to Game Pass Console. They could still differentiate Ultimate with the whole PC/Console Game Pass and EA play bundle while keeping cloud gaming to ultimate only.

That’s terrible. I guess it’s a way to “force” people into the higher ultimate tier.

Yeah, if they want any level of sales of Console Gamepass over Gamepass Core, then they will need to add Multiplayer to Gamepass Console.

Now, for me I'm still going to be using Ultimate because I have a PC and now a Series X (Through the Xbox All Access program which also gives 2 years of Gamepass Ultimate)
